Answer:

-4,651.42N

Explanation:

Since we are not asked what to find, we can calculate the force applied by the track as shown;

F = ma

F = m(v-u)/t

Substitute the given value

F = 4400(7.6-52)/42

F = 4400(-44.4)/42

F = -4,651.43N

Hence the required force is -4,651.42N

Complete Question:

Football player A has a mass of 110 kg, and he is running down the field with a velocity of 2 m/s. Football player B has a mass of 120 kg and is stationary. What is the total momentum after the collision?

Answer:

Total momentum = 220 Kgm/s.

Explanation:

Given the following data;

For footballer A

Mass, M1 = 110kg

Velocity, V1 = 2m/s

For footballer B

Mass, M1 = 120kg

Velocity, V1 = 0m/s since he's stationary.

To find the total momentum;

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

[tex] Momentum = mass * velocity [/tex]

a. To find the momentum of A;

[tex] Momentum \; A = 110 * 2 [/tex]

Momentum A = 220 Kgm/s.

b. To find the momentum of B;

[tex] Momentum \; B = 120 * 0 [/tex]

Momentum B = 0 Kgm/s.

c. To find the total momentum of the two persons;

[tex] Total \; momentum = Momentum \; A + Momentum \; B [/tex]

Substituting into the equation, we have;

[tex] Total \; momentum = 220 + 0 [/tex]

Total momentum = 220 Kgm/s.

The total momentum after the collision will be 220 Kgm/s.Momentum is equal to its mass multiplied by its velocity.

The measurement of mass in motion is called momentum. Momentum is equal to its mass multiplied by its velocity. Mathematically it is given as;

Momentum = Mass x Velocity

The given data in the problem is;

m₁ is the mass of player A= 110 kg

m₂  is the mass of player B= 120 kg

v₁ is the velocity of player A= 2m/s

v₂  is the velocity of player B=0m/s

P is the total momentum=?

The momentum of player A;

[tex]\rm P_A= m_A \times v_A \\\\ \rm P_A= 110 \times 2 \\\\ \rm P_A= 220 \ Kgm/sec[/tex]

The momentum of player B;

[tex]\rm P_B= m_B \times v_B \\\\ \rm P_B= 120 \times 0 \\\\ \rm P_B= 0 \ Kgm/sec[/tex]

The total momentum is given by;

Total momentum = momentum of the player A+ momentum of the player B

[tex]\rm P= P_A+P_B \\\\ \rm P= 220+0 \\\\ \rm P=220 \ m/sec[/tex]

Hence the total momentum after the collision will be 220 Kgm/s

In this problem they indicate the pressure at the bottom of the lake and the density of the water, for which they must ask what is the depth of the lake.

The pressure is given by the expression

           P = [tex]P_{atm}[/tex] + rho g h

           P - P_{atm} = rho g h

The gauge pressure value is P- P_{atm} = 3 105 N / m²

Answer:

6.075×10²³ Electrons

Explanation:

From the question,

Q = it............................. Equation 1

Where Q = quantity of charge, i = current, t = time.

Given: i = 27 A, t = 1 hours = 1×60×60 = 3600 seconds.

Substitute these values into equation 1

Q = 27×3600

Q = 97200 C.

If, one electron = 1.6×10⁻¹⁹ C,

Therefore, n electron = 97200×1/1.6×10⁻¹⁹ C.

n = 6.075×10²³ Electrons

The relationship between kinetic energy and speed is directly proportional.

The given problem is based on the Kinetic energy. The energy possessed by any object by virtue of its motion is known as kinetic energy of an object. The mathematical expression for the kinetic energy is given as,

[tex]KE = \dfrac{1}{2}mv^{2}[/tex]

Here,

m is the mass of object.

v is the speed of object.

the mass of any object remains constant. Then, the kinetic energy is given as,

[tex]KE \propto v^{2}[/tex]

Thus, we can conclude that the kinetic energy is directly proportional to the square of speed of object.

Answer:

a)  v = 126.5 m / s,  b)   λ₁ = 1.6 m,   λ₂ = 0.8 m, λ₃ = 0.533 m,   f1 = 79 Hz,    

λ₂ = 0.8 m,   f₃ = 237 Hz

Explanation:

This is an exercise we are going to solve in parts, let's start by looking for the speed of the wave in the string.

         v = [tex]\sqrt { \frac{T}{ \mu } }[/tex]

the rope tension is T = 90 N and the density can be calculated

         μ = m / l

let's calculate

         μ = 4.5 10⁻³ / 0.80

         μ = 5.625 10⁻³  kg/m

let's calculate the speed

         v = [tex]\sqrt{ \frac{90 }{5.625 \ 10^{-3}} }[/tex]

         v = 126.5 m / s

For the second part there is a process of resonance in the string. The points where it is attached are nodes so, if L is the length of the chord

         L = ½ λ         1st harmonic

         L = 2/2 λ      2nd harmonic

         L = 3/2 λ      3rd harmonic

         L = n/2 λ      n harmonic

the wavelength of the first three harmonics is requested

let's calculate

          λ₁ = 2L

          λ₁ = 2 0.8

          λ₁ = 1.6 m

          λ₂ = L

          λ₂ = 0.8 m

          λ₃ = ⅔ L

          λ₃ = ⅔ 0.8

          λ₃ = 0.533 m

To calculate the frequency we use that the speed is related to the wavelength and the frequency

           v = lam f

           f = v / lam

we calculate

           f1 = 126.5 / 1.6

           f1 = 79 Hz

           f2 = 126.5 / 0.8

           f2 = 158 Hz

           f3 = 126.5 / 0.533

           f3 = 237 Hz
