***The diagram was not given for the question and I drew my own***

3. Above is a diagram of a 2 kg ball on a ramp of 0.5 m in height. It is released from rest and rolls down a frictionless ramp. It travels 3 m before reaching the bottom of the ramp.

a. How much work would gravity do on the ball by the time the ball reaches the bottom of the ramp?

b. How much work would the ramp do on the ball by the time the ball reaches the bottom of the ramp?

c. What would the ball’s final velocity be by the time it reaches the bottom of the ramp?

Now assume that there 0.1 N of frictional force between the ball and the ramp.

d. How much work would friction do on the ball?

e. What would the final velocity of the ball be at the bottom of the ramp this time?

A crate of fruit with a mass of 39.0 kg and a specific heat capacity of 3600 J/(kg⋅K) slides 8.70 m down a ramp inclined at an angle of 38.3 degrees below the horizontal. Part A If the crate was at rest at the top of the incline and has a speed of 2.65 m/s at the bottom, how much work Wf was done on the crate by friction? Use 9.81 m/s2 for the acceleration due to gravity and express...

A small rock with mass 0.20 kg is released from rest at point A, which is at the top edge of a large, hemispherical bowl with radius R = 0.50 m. Assume that the size of the rock is small compared to R, so that the rock can be treated as a particle, and assume the rock slides rather then rolls. The work done by friction on the rock when it moves from point A to point B at the...

A 350 kg crate is being LOWERED by a person a distance 10 m with a force (FP) of 80 N(the person is pulling upward but the crate is moving downward). The rough ramp exerts a constant force of friction of 70 N. The angle that the ramp makes with the 0 floor is 30 . (a) Draw a free body diagram for the crate. (b) What is the work done by the person on the crate? (c) What is...
