The force acting on the mass is 98 N (Newtons).
The force acting on the mass can be determined using Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a).
In this case, the force acting on the mass is the gravitational force, given by the equation F = mg, where g is the acceleration due to gravity (approximately 9.8 m/s^2).
Given that the mass of the particle is 10 kg, we can calculate the force acting on it as follows:
F = mg
F = 10 kg * 9.8 m/s^2
Therefore, the force acting on the mass is 98 N (Newtons).

the hydrogen in interstellar space near a star is largely ionized by the high-energy photons emitted from the star. such regions are termed h ii regions. suppose a ground- state hydrogen atom absorbs a photon with a wavelength of 65 nm. calculate the kinetic energy of the ejected electron. (this is the gas-phase analog of the photoelectric effect for solids.)
In interstellar space near a star, hydrogen atoms are largely ionized by the high-energy photons emitted from the star, resulting in H II regions. In this gas-phase analog of the photoelectric effect for solids, we are given that a ground-state hydrogen atom absorbs a photon with a wavelength of 65 nm.
To calculate the kinetic energy of the ejected electron, we can use the equation:
E = hc/λ
where E is the energy of the photon, h is Planck's constant (6.626 x [tex]10^-34[/tex] J.s), c is the speed of light (3.0 x [tex]10^8[/tex]m/s), and λ is the wavelength of the photon.
First, we need to convert the wavelength from nanometers to meters. Since 1 nm is equal to 1 x [tex]10^-9[/tex]m, the wavelength is 65 nm x (1 x [tex]10^-9[/tex]m/1 nm) = 6.5 x[tex]10^-8[/tex] m.
Next, we can substitute the values into the equation:
E = (6.626 x[tex]10^-34[/tex]J.s) * (3.0 x[tex]10^8[/tex] m/s) / (6.5 x [tex]10^-8[/tex] m)
By performing the calculation, we find that the energy of the photon is approximately 3.046 x 10^-19 J.
In the gas-phase analog of the photoelectric effect, the kinetic energy of the ejected electron can be found using the equation:
K.E. = E - Φ
where K.E. is the kinetic energy, E is the energy of the photon, and Φ is the work function of the atom or ion.
Since the electron is being ejected from a hydrogen atom, we can assume that the work function is equal to the ionization energy of hydrogen, which is 2.18 x [tex]10^-18[/tex]J.
Substituting the values into the equation, we have:
K.E. = (3.046 x[tex]10^-19[/tex] J) - (2.18 x[tex]10^-18[/tex] J)
Calculating this, we find that the kinetic energy of the ejected electron is approximately -1.8755 x 10^-18 J.

A cylinder with a moving piston expands from an initial volume of 0.250 L against an external pressure of 2.20 atm. The expansion does 488 J of work on the surroundings. What is the final volume of the cylinder
The final volume of the cylinder can be calculated using the equation for work done by an expanding gas:
Work = P * ΔV
where Work is the work done on the surroundings (given as 488 J), P is the external pressure (given as 2.20 atm), and ΔV is the change in volume.
Rearranging the equation, we can solve for ΔV:
ΔV = Work / P
Plugging in the given values, we have:
ΔV = 488 J / 2.20 atm
To calculate the final volume, we need to know the initial volume of the cylinder. The problem states that the initial volume is 0.250 L.
So, the final volume can be found by adding the initial volume to the change in volume:
Final Volume = Initial Volume + ΔV
Substituting the values, we have:
Final Volume = 0.250 L + (488 J / 2.20 atm)
To calculate the final volume in liters, we need to convert the work done from joules to liters-atmospheres using the conversion factor:
1 L-atm = 101.3 J
Therefore:
Final Volume = 0.250 L + (488 J / 2.20 atm) * (1 L-atm / 101.3 J)
Simplifying this equation will give you the final volume of the cylinder.
The final volume of the cylinder can be calculated by adding the initial volume to the change in volume, which is equal to the work done divided by the external pressure. By substituting the given values and converting the units, the final volume can be determined accurately.

An object has a position given by = [2.0 m + ( 5.00 m/s)t] + [3.0 m - , where quantities are in SI units. What is the speed of the object at time
The speed of the object at time t = 2 seconds is 1.00 m/s.
To determine the speed of the object at a given time, we need to find the magnitude of its velocity vector at that time.
Given:
Position vector r(t) = [2.0 m + (5.00 m/s)t] + [3.0 m - t² m]
To find the velocity vector v(t), we take the derivative of the position vector with respect to time:
v(t) = d[r(t)]/dt
v(t) = d/dt [2.0 m + (5.00 m/s)t] + d/dt [3.0 m - t² m]
v(t) = 5.00 m/s + d/dt [3.0 m - t² m]
The derivative of a constant term is zero, so the velocity vector simplifies to:
v(t) = 5.00 m/s - d/dt (t²) m
Taking the derivative of t² with respect to time:
v(t) = 5.00 m/s - 2t m/s
Now, we can calculate the magnitude of the velocity vector (speed) at a specific time t:
Speed = |v(t)| = |5.00 m/s - 2t m/s|
To find the speed at a given time, substitute the appropriate value of t into the expression and calculate the magnitude.
For example, if t = 2 seconds:
Speed = |5.00 m/s - 2(2 s) m/s|
= |5.00 m/s - 4 m/s|

An astronaut in space has a certain amount of angular momentum (H1), at some time later she has an angular momentum of H2. If H2 is greater than H1, what can you assume happened to the astronaut
If the astronaut's angular momentum (H2) is greater than her initial angular momentum (H1), we can assume that something happened to change her angular momentum. Angular momentum is a property of rotating objects and is conserved in the absence of any external torques.
There are a few possible scenarios that could have led to an increase in angular momentum:
1. The astronaut could have extended her arms or legs outward while rotating. This action would increase her moment of inertia, which is a measure of an object's resistance to changes in rotational motion. By increasing her moment of inertia, the astronaut can increase her angular momentum without changing her angular velocity.
2. The astronaut could have changed her rotational speed while keeping her moment of inertia constant. For example, she could have pulled in her limbs closer to her body, effectively reducing her moment of inertia. According to the conservation of angular momentum, a decrease in moment of inertia would result in an increase in rotational speed to maintain the same angular momentum.
3. The astronaut could have experienced an external torque that acted on her body, causing a change in her angular momentum. For instance, if the astronaut used a propellant to push herself off from a surface, the force exerted would create a torque on her body, changing her angular momentum.

Which of the following characteristics of a single star (one that moves through space alone) is it difficult to measure directly
Determining the mass of a star that moves through space alone cannot be done through direct observation and requires indirect methods based on gravitational interactions and theoretical models.
Measuring the mass of a single star directly is challenging because it cannot be directly observed or measured. Unlike other characteristics such as luminosity, temperature, and chemical composition, which can be determined through observations and spectral analysis, measuring the mass of a star requires indirect methods.
One approach to estimating a star's mass is through studying its gravitational interactions with other celestial objects. This involves observing the motion of the star within a binary system or its effects on nearby objects. By measuring the orbital characteristics and applying Kepler's laws of motion, scientists can infer the mass of the star based on its gravitational influence.
Another method is through theoretical models that incorporate observable properties of the star, such as its luminosity and temperature, and compare them with stellar evolutionary tracks. These models provide estimates of the star's mass based on the understanding of stellar physics and evolutionary processes.
However, both these methods have inherent uncertainties and limitations, making the direct measurement of a single star's mass a challenging task in astrophysics.

A heat engine with 60.0% efficiency releases of energy into the environment. How much energy does the engine take in as heat
The efficiency of a heat engine is the ratio of the work done by the engine to the heat input. So, if the efficiency of the heat engine is 60.0%, then 60.0% of the heat input is converted into work, and the remaining 40.0% is released into the environment.
Let's say that the heat engine takes in 100 J of heat. Then, 60.0 J of this heat is converted into work, and 40.0 J is released into the environment.
Therefore, the heat engine takes in 100 J of heat to produce 60.0 J of work.
Here is the formula for calculating the efficiency of a heat engine:
efficiency = work / heat input
In this case, the efficiency is 60.0%, the work is 60.0 J, and the heat input is 100 J. So, we can plug these values into the formula to get:

The work done by friction on the curling stone is -136 Joules (J).To calculate the work done by friction, we first need to find the force and distance involved.
Given:
Mass of the curling stone (m) = 17 kg
Initial speed (v) = 4.0 m/s
Time taken to come to rest (t) = 10 s
First, let's calculate the deceleration (a) of the curling stone using the equation:
a = (final velocity - initial velocity) / time
a = (0 - 4.0) / 10
a = -0.4 m/s^2
The force (F) acting against the curling stone's motion can be calculated using Newton's second law of motion:
F = mass x acceleration
F = 17 kg x -0.4 m/s^2
F = -6.8 N
Since the curling stone comes to rest, the work done by friction is equal to the work done against the force of friction. The formula for work (W) is:
W = force x distance
However, we don't have the distance directly provided in the question. To calculate the distance, we can use the kinematic equation:
v^2 = u^2 + 2as
Since the final velocity (v) is 0 and the initial velocity (u) is 4.0 m/s, we can rearrange the equation to solve for distance (s):
s = (v^2 - u^2) / (2a)
s = (0^2 - 4.0^2) / (2 x -0.4)
s = -16 / (-0.8)

The values for force (Fe) when q₂ is 4 μC and when q₂ is 8 μC do not support a linear relationship between charge and force.
In the given question, we are comparing the values for force (Fe) when q₂ is 4 μC and when q₂ is 8 μC. To determine whether there is a linear relationship between charge and force, we need to analyze the data.
When q₂ is 4 μC, let's assume the corresponding force is Fe₁. When q₂ is 8 μC, let's assume the corresponding force is Fe₂. By comparing the two forces, we can evaluate if the change in charge leads to a proportional change in force.
If there is a linear relationship between charge and force, we would expect that doubling the charge (from 4 μC to 8 μC) would result in a doubling of the force. However, this may not be the case.
Upon comparing Fe₁ and Fe₂, if Fe₂ is exactly double the value of Fe₁, then it would suggest a linear relationship. On the other hand, if Fe₂ is less than double the value of Fe₁ or greater than double the value of Fe₁, it indicates a non-linear relationship.
Therefore, by examining the specific values of Fe when q₂ is 4 μC and when q₂ is 8 μC, we can determine if they exhibit a linear relationship or not.

on earth, froghoppers can jump upward with a takeoff speed of 2.82 m/s. suppose some of the insects are taken to an asteroid. if the asteroid is small enough, the froghoppers can jump free of it and escape into space. what is the diameter ????1 (in kilometers) of the largest spherical asteroid from which they could jump free? assume an asteroid density of 2.24 g/cm3.
The diameter of the largest spherical asteroid from which the froghoppers could jump free is approximately 51.4 kilometers.
To determine the diameter of the largest spherical asteroid from which the froghoppers could jump free, we need to consider the escape velocity required for the froghoppers to overcome the gravitational pull of the asteroid. The escape velocity can be calculated using the formula:
v_escape = sqrt((2 * G * M) / R),
where G is the gravitational constant (approximately 6.67430 x 10^-11 m^3 kg^-1 s^-2), M is the mass of the asteroid, and R is the radius of the asteroid.
We can relate the mass of the asteroid to its density and volume using the formula:
M = (4/3) * π * ρ * R^3,
where ρ is the density of the asteroid.
By substituting the expression for M into the escape velocity formula, we get:
v_escape = sqrt((8 * G * π * ρ * R^2) / 3).
Given that the takeoff speed of the froghoppers is 2.82 m/s, we can set the escape velocity equal to this speed:
2.82 = sqrt((8 * G * π * ρ * R^2) / 3).
Solving for R, we find:
R = sqrt((3 * 2.82^2) / (8 * G * π * ρ)).
Substituting the values for G (gravitational constant) and ρ (asteroid density), we have:
R = sqrt((3 * 2.82^2) / (8 * 6.67430 x 10^-11 * π * 2.24)).
Calculating this expression, we get:
R ≈ 2568.4 meters.
Finally, we can convert the radius to diameter by multiplying by 2 and converting from meters to kilometers:
Diameter ≈ 2 * 2568.4 meters ≈ 5136.8 meters ≈ 51.4 kilometers.
Therefore, the diameter of the largest spherical asteroid from which the froghoppers could jump free is approximately 51.4 kilometers.

We set the final solution as the calculated values for rp, rd, and ra.
When a charged particle moves through a magnetic field perpendicular to its velocity, it experiences a force called the magnetic Lorentz force. This force acts as a centripetal force, causing the particle to move in a circular path. The radius of this circular path is given by the equation:
r = (mv) / (|q|B)
where r is the radius, m is the mass of the particle, v is its velocity, q is its charge, and B is the magnetic field strength.
Given the information provided, we can calculate the radius of the proton's circular path using its charge, mass, and velocity. Since the proton has a charge of e and a mass of mp, its radius (rp) can be expressed as:
rp = (mp * vp) / (|e| * B)
Similarly, we can calculate the radius of the deuteron's circular path (rd) and the alpha particle's circular path (ra) using their respective charges, masses, and velocities.
The velocity of each particle can be determined using the principle of conservation of energy. The potential difference δv is converted into kinetic energy, so we have:
(1/2)mv² = eδv
where v is the velocity of each particle.
Since the mass and charge are known for each particle, we can solve for the velocity and substitute it back into the radius equation to find the respective radii.

In Beijing, a restaurant keeps a pot of chicken broth simmering continuously. Every morning, it is topped up to contain 10.0L of water along with a fresh chicken, vegetables, and spices. The molar mass of water is 18.0 g/mol .(a) Find the number of molecules of water in the pot.
There are approximately 3.345 x 10²⁶ molecules of water in the pot
To find the number of molecules of water in the pot, we need to calculate the number of moles of water first. The molar mass of water is 18.0 g/mol. Given that the pot contains 10.0L of water, we can use the following formula to find the number of moles:
moles = mass/molar mass mass = volume x density
The density of water is approximately 1 g/mL.
Therefore, the mass of 10.0L of water can be calculated as:
mass = 10.0L x 1000 mL/L x 1 g/mL = 10,000 g
Now, we can calculate the number of moles: moles = 10,000 g / 18.0 g/mol ≈ 555.56 mol
Since 1 mole of water contains Avogadro's number of molecules (approximately 6.022 x 10²³), we can find the number of molecules of water in the pot:
number of molecules = moles x Avogadro's number
number of molecules ≈ 555.56 mol x 6.022 x 10²³ molecules/mol ≈ 3.345 x 10²⁶ molecules
Therefore, there are approximately 3.345 x 10²⁶ molecules of water in the pot.

Suppose there is 1.001.00 l of an aqueous buffer containing 60.060.0 mmol of formic acid (pa=3.74)(pka=3.74) and 40.040.0 mmol of formate. calculate the ph of this buffer.
With the application of the Henderson-Hasselbalch equation, the calculated pH of the concerned buffer in the question is approximately 3.56.
The Henderson-Hasselbalch equation refers to the pH of a particular buffer solution which denotes the concentrations of the acid and its conjugate base. It is expressed as:
pH = pKa + log[tex]([A-]/[HA])[/tex]
Where pH is the desired pH, pKa is the acid dissociation constant, [A-] is the concentration of the conjugate base, and [HA] is the concentration of the acid.
In this case, the formic acid concentration is 60.0 mmol and the formate concentration is 40.0 mmol. The pKa of mentioned formic acid in the question is obtained to be 3.74.
Substituting the values into the Henderson-Hasselbalch equation, we get:
pH = 3.74 + log(40.0/60.0)
Simplifying the logarithmic term, we have:
pH = 3.74 + log(2/3)
To measure the actual numeric value of the logarithm, the following must be done:
pH = 3.74 - 0.18
Therefore, the pH of the buffer is approximately 3.56.

2. If you tested a pendulum, what happens to the period of the pendulum as the length of the string increases
The period of a pendulum refers to the time it takes for the pendulum to complete one full swing back and forth.
When the length of the string increases, the period of the pendulum also increases. This means that it takes longer for the pendulum to complete one full swing.
To understand why this happens, let's consider the factors that affect the period of a pendulum. The period is influenced by the length of the string and the acceleration due to gravity. The longer the string, the greater the distance the pendulum has to travel in each swing. As a result, it takes more time for the pendulum to complete one full swing.
To visualize this, imagine two pendulums side by side: one with a shorter string and one with a longer string. When both pendulums are released at the same time, the pendulum with the longer string will take more time to complete each swing compared to the one with the shorter string.
In summary, as the length of the string increases, the period of the pendulum also increases, meaning it takes longer for the pendulum to complete one full swing. This is because the pendulum has to cover a greater distance in each swing.

a ball of mass m is attached to a strong of lenght l. it is being wung in a vertical cirlce iwht ienouguh speed so thta the string remians taut throughout the balls motion
When the ball is swung in a vertical circle with enough speed, the tension in the string remains constant because it balances the weight of the ball and provides the necessary centripetal force.
When a ball is swung in a vertical circle, it experiences both gravitational force and tension in the string. The tension in the string provides the centripetal force needed to keep the ball moving in a circular path.
To understand why the tension remains constant, let's break down the forces acting on the ball at different points in the motion:
1. At the top of the circle: At this point, the tension in the string is at its maximum because it must counteract the weight of the ball pulling it downwards. The net force acting on the ball is the difference between the tension and the weight, which results in a net inward force towards the center of the circle.
2. At the bottom of the circle: Here, the tension in the string is at its minimum because it only needs to support the weight of the ball. The net force acting on the ball is the sum of the tension and the weight, resulting in a net inward force towards the center of the circle.
In both cases, the net force towards the center of the circle provides the necessary centripetal force to keep the ball moving in a circular path. This is why the string remains taut throughout the ball's motion.

cart 111 of mass mmm is traveling with speed v 0v 0 v, start subscript, 0, end subscript in the x xplus, x-direction when it has an elastic collision with cart 222 of mass 2m2m2, m that is at rest.
Cart 1 of mass m is traveling with speed v, in the +x-direction when it has an elastic collision with cart 2 of mass 2m traveling with speed vo in the -x-direction. The expression for the velocities of the carts after the elastic collision is:
v1' = 3v + vo,v2' = -mvo / 2
Let's denote the initial velocity of cart 1 as v1, the initial velocity of cart 2 as v2, and the final velocities of cart 1 and cart 2 as v1' and v2', respectively, after the collision.
Conservation of momentum states that the total momentum before the collision is equal to the total momentum after the collision:
m × v1 + 2m × v2 = m × v1' + 2m × v2'
Applying the signs according to the given directions:
mv + 2m × (-vo) = m × v1' + 2m × v2'
Simplifying the equation:
mv - 2mvo = m × v1' + 2m × v2'
Next, conservation of kinetic energy states that the total kinetic energy before the collision is equal to the total kinetic energy after the collision:
(1/2) × m × v^2 + (1/2) × (2m) × (-vo)^2 = (1/2) × m × (v1'^2) + (1/2) × (2m) × (v2'^2)
Simplifying the equation:
(1/2) × m × v^2 + m × vo^2 = (1/2) × m × (v1'^2) + 2m × (v2'^2)
Now, we have a system of two equations with two unknowns (v1' and v2'). We can solve these equations to find the velocities of the carts after the collision.
To solve the system, we can rearrange the momentum conservation equation to express v1' in terms of v and vo:
v1' = (mv + 2mvo - 2mv2') / m
Substituting this expression for v1' in the kinetic energy conservation equation:
(1/2) × m × v^2 + m × vo^2 = (1/2) × m × [(mv + 2mvo - 2mv2') / m]^2 + 2m × v2'^2
Simplifying and solving for v2':
(1/2) × m × v^2 + m × vo^2 = (1/2) × m × (v^2 + 4vo^2 + 4v^2v2'^2 / m^2 - 4vvo - 4v2'vo)
Rearranging terms:
(1/2) × m × v^2 - (1/2) × m × v^2 - 4v2'vo = -2mvo^2 + 4mvo^2
-4v2'vo = 2mvo^2
v2' = -mvo / 2
Finally, substituting this expression for v2' back into the momentum conservation equation, we can find v1':
v1' = (mv + 2mvo - 2m ×(-mvo / 2)) / m
Simplifying:
v1' = 3v + vo
Therefore, the expression for the velocities of the carts after the elastic collision is:
v1' = 3v + vo
v2' = -mvo / 2
The question should be:
Cart 1 of mass m is traveling with speed v, in the +x-direction when it has an elastic collision with cart 2 of mass 2m traveling with speed vo in the -x-direction. Obtain an expression for the velocities of the carts after the collision?

An electron is confined to move in the x y plane in a rectangle whose dimensions are Lₓ and Ly . That is, the electron is trapped in a two-dimensional potential well having lengths of Lₓ and Ly . In this situation, the allowed energies of the electron depend on two quantum numbers nₓ and ny and are given byE = h²/8me (n²x/L²ₓ + n²y/L²y) Using this information, we wish to find the wavelength of a photon needed to excite the electron from the ground state to the second excited state, assuming Lₓ = Ly = L .(h) What is the wavelength of a photon that will cause the transition between the ground state and the second excited state?
The wavelength of the photon that will cause the transition between the ground state and the second excited state is given by λ = (h/8me) * (L²/14).
To find the wavelength of a photon needed to excite the electron from the ground state to the second excited state in a two-dimensional potential well with dimensions Lₓ and Ly, we can use the energy equation E = h²/8me (n²ₓ/L²ₓ + n²y/L²y), where E is the energy, h is Planck's constant, mₑ is the mass of the electron, and nₓ and nₓ are the quantum numbers.
In this case, we are assuming Lₓ = Ly = L, so the equation simplifies to E = h²/8me (n²ₓ/L² + n²y/L²).
The ground state corresponds to nₓ = 1 and nₓ = 1, while the second excited state corresponds to nₓ = 3 and nₓ = 3.
To find the energy difference between the two states, we can subtract the energy of the ground state from the energy of the second excited state:
ΔE = E₂ - E₁ = h²/8me ((3²/L² + 3²/L²) - (1²/L² + 1²/L²))
ΔE = h²/8me ((9/L² + 9/L²) - (1/L² + 1/L²))
ΔE = h²/8me (16/L² - 2/L²)
ΔE = h²/8me (14/L²)
Now, using the equation for the energy of a photon, E = hc/λ, where c is the speed of light and λ is the wavelength, we can equate the energy difference to the energy of the photon:
ΔE = hc/λ
h²/8me (14/L²) = hc/λ
Simplifying the equation:
λ = (h/8me) * (L²/14)
Therefore, the wavelength of the photon is given by λ = (h/8me) * (L²/14).

A stonecutter's chisel has an edge area of 1.0 cm 2 . if the chisel is struck with a force of 50 n, what is the pressure exerted on the stone?
The pressure exerted on the stone by the stonecutter's chisel can be calculated using the formula:
Pressure = Force / Area
In this case, the force applied to the chisel is 50 N and the edge area of the chisel is 1.0 cm^2. However, it is important to convert the area to square meters to ensure consistent units.
To convert the area from cm^2 to m^2, we need to divide it by 10,000 since there are 10,000 square centimeters in a square meter. So, the area in square meters would be 1.0 cm^2 / 10,000 = 0.0001 m^2.
Now we can calculate the pressure:
Pressure = 50 N / 0.0001 m^2
Pressure = 500,000 N/m^2
Therefore, the pressure exerted on the stone by the chisel is 500,000 N/m^2.
It is worth noting that this is a relatively high pressure value. Pressure is a measure of the force applied over a given area, and in this case, the small area of the chisel's edge results in a high pressure on the stone when struck with a force of 50 N. This high pressure allows the chisel to effectively cut through the stone.

The pressure exerted on the stone by the chisel is 500,000 pascals.
Explanation :
The pressure exerted on the stone can be calculated by dividing the force applied by the area over which the force is distributed. In this case, the force applied is 50 N and the edge area of the chisel is 1.0 cm^2.
To find the pressure, we need to convert the area to square meters since the SI unit for pressure is pascals (Pa), which is equivalent to N/m^2.
1 cm^2 is equal to 0.0001 m^2.
Now, we can calculate the pressure by dividing the force by the area:
Pressure = Force / Area
Pressure = 50 N / 0.0001 m^2
Pressure = 500,000 N/m^2 or 500,000 Pa
In summary, when a force of 50 N is applied to a stonecutter's chisel with an edge area of 1.0 cm^2, the pressure exerted on the stone is 500,000 pascals.

From the information given, we know that the rocket has a mass of 8.00 kg and is moving upward from the launch pad. The force exerted by the burning fuel on the rocket is time-varying and can be described by the equation f(t), where t represents time. The work done by the force is given by the equation W = ∫f(t) * ds, where ds represents an infinitesimally small displacement.
To determine the total work done by the rocket, we need to integrate the force over the distance traveled. Let's assume that the rocket moves a distance d.
The work done by the force is given by the equation W = ∫f(t) * ds, where ds represents an infinitesimally small displacement.
Since the force is upward and the displacement is also upward, the angle between the force and the displacement is 0 degrees, which means the work done is positive.
To solve this equation, we need to know the specific equation for the force f(t). Once we have that, we can integrate it with respect to displacement to find the total work done by the rocket.
