3. Some surfboards weigh more than others. How does a board’s weight affect the amount of force needed to get it moving?

Answers

The weight of the board influences the amount of effort required to move it because if it were too heavy, it would just sink, and if it were too light, it would simply float away.

The gravitational pull of a second, significantly bigger object, like the Earth or Moon, on a first object is known as weight. According to the universal law of gravity, any two objects will gravitate toward one another due to their masses with a force that is inversely proportional to the square of the distance between them and precisely proportional to the product of their masses. The source of weight is this law. Because of this, larger objects naturally weigh more when placed in the same location. However, the further an object is from the Earth, the less weight it has. An object's weight at the South Pole is somewhat higher than its weight at the North Pole because the Earth's polar radius is slightly less than its equatorial radius.

a child and his sled have a combined mass of 40 kg. the sled/child system has a speed of 5 m/s speed at the top of a 10 m high slope. the sled and child descend the hill linearly along a distance of 100 m. determine the speed of the child and sled at the bottom of the 100 m slope, if the force of friction between the sled and snow is 20 n.

Answers

The speed of the child and sled at the bottom of the slope is 11 m/s.

What is mechanical energy?

Mechanical energy, is the sum of potential energy and kinetic energy. The principle of conservation of mechanical energy states that mechanical energy is constant if an isolated system is subjected to only conservative forces.

Combined mass (m) = 40 kg

Speed at top of slope (v) = 5 m/s

Height of slope (h) = 10 m

Entire range of the slope (d) = 100 m

Force of friction (F) = -20 N

Work done by friction (W) = F × d

= -20 × 100

= -2000 J

Kinetic energy (KE) of sled at the top of slope = ¹/₂ mv²

= ¹/₂ × 40 × 5²

= 500 J

Potential energy (PE) of sled at the top of slope = mgh

= 40 × 9.8 × 10

= 3920 J

Now, total energy (E) of sled/child system at the top of slope = KE + PE

= 500 + 3920

= 4420 J

So, the energy left at the bottom of slope:

4420 J - 2000 J

= 2420 J

Now this lost energy is converted into kinetic energy of the system:

KE = ¹/₂ mv²

2420 J = ¹/₂ × 40 × v²

v² = 121

v = 11 m/s

The conservation of momentum in an elastic collision is conserved whereas in an inelastic collision it is conserved but kinetic energy is lost.

When an elastic collision occurs in an isolated system, the total momentum of the object system is conserved. Assuming no net external forces acting on the objects, the momentum of all objects before the collision equals the momentum of all objects after the collision.

An inelastic collision is a type of collision that occurs between two objects in which energy is lost. In an inelastic collision, momentum is conserved, but kinetic energy is not. Most collisions in everyday life are inelastic in nature.

an 80.0 kg astronaut carrying a 15.0 kg tool kit is drifting away from the space station at a speed of 1.25 m/s. a) if she throws the tool kit away from the space station with a speed of 6.00 m/s, what is her final speed and direction?

Answers

The final speed of the astronaut at the space station is 0.36 m/s and the direction will be opposite to the direction of the tool kit thrown.

The mass of the astronaut = 80 kg

The mass of the tool kit = 15 kg

The speed of the space station = 1.25 m/s

The speed of the tool kit threw = 6 m/s

The final speed of the astronaut can be found using the conservation of momentum formula,

           [tex]\displaystyle m_{1}v_{f1} + m_{2}v_{f2} = m_{1}v_{i1} + m_{2}v_{i2}[/tex]

where m₁ is the mass of the astronaut

           m₂ is the mass of the tool kit

           [tex]\displaystyle v_{i1}[/tex] and [tex]\displaystyle v_{i2}[/tex] is the speed of the space station

           [tex]\displaystyle v_{f1}[/tex] is the speed of the astronaut after throwing the toolkit

Let us substitute the known values in the above equation, we get

              (80 x [tex]\displaystyle v_{f1}[/tex]) + (15 x 6) = (80 x 1.25) + (15 x 1.25)

                     (80 x [tex]\displaystyle v_{f1}[/tex]) + 90 = 100 + 18.75

                              80 x [tex]\displaystyle v_{f1}[/tex]   = 118.75 - 90

                                80 x [tex]\displaystyle v_{f1}[/tex] = 28.75

                                        [tex]\displaystyle v_{f1}[/tex] = 28.75 / 80

                                              = 0.36 m/s

Therefore, the final speed of the astronaut is 0.36 m/s

By newton's third law, for every action, there will be an equal and opposite reaction. Thus, the direction of the astronaut's direction will be against the direction of the tool kit thrown.

enceladus is an icy moon of saturn experiencing tidal forces because of an elliptical orbit due to an orbital resonance with another moon dione. what are the consequences of tidal heating of enceladus because of this elliptical orbit?

Answers

The main consequence of tidal heating on Enceladus because of this elliptical orbit is that it occasionally brings the moon closer to Saturn and occasionally farther away.

When Dione, a bigger moon, orbits Saturn once, Enceladus orbits twice. Enceladus' orbit is made elliptical by Dione's gravity. This causes tidal heating inside the moon, and the following effects also:

The extremely hot geysers on the Enceladus moon, which shoot water into space, are caused by this.The "tiger stripes" in Enceladus' south pole, which are active fissures, are where the particles are released.The presence of salt in the plumes suggests that the frozen shell may be hiding an ocean of liquid water.

But the ultimate cause of the geological activity on this moon had remained a mystery. Instead of a circular orbit, Enceladus orbits Saturn in an elliptical distortion. Saturn's gravity pulls and squeezes the moon as a result, heating its innards and allowing geological activity on the frozen moon.

Answers

Catching the ball would result in a reduced speed.

Simply put, what is a momentum?

A quality that a moving body possesses due to its mass and motion, and which is equal to the sum of the body's mass and velocity.

You ought to catch the ball to reduce the pace of the skateboard.

Assume that "M" is the ball's mass, "m" is the skater's mass, "V0" is the speed at which the ball was thrown, and "Vs" is the skater's speed.

If the skater catches the ball according to the law of conservation of momentum:

[tex]M*V_{0}+ m*0=(m + M)*V_{s}[/tex]

[tex]V_{s}=\frac{M*(V_{0}-V_{s })}{m}[/tex]

The ball will assume a new velocity with a direction opposite to that of the skater if the skater deflects the ball; let that new velocity be "Vb":

Since:

[tex]V_{0}-V_{s} < V_{0}+V_{b}[/tex]

Catching the ball would result in a reduced speed.

which graph best represents the relationship between the velocity of an object thrown straight upward from Earth's surface and the time that elapses while it is in the air?

Answers

The graph that best represents the relationship between the velocity of an object thrown straight upward from the Earth's surface and the time that elapses while it is in the air is (option D)

What is Velocity?

Velocity is the directional speed of a moving object as an indicator of its rate of change in location as perceived from a certain frame of reference and measured by a specific time standard.

In other words, velocity is the primary indication of an object's location as well as its speed. It is defined as the distance traveled by an item in one unit of time. The displacement of an item in unit time is defined as velocity.

The equation that speaks to the velocity at a vertically upwards object that is accelerated against gravity and time is given as:

v = u + at; where

v = velocity

u = point from which the object starts to move

a is acceleration; and

t is time.
