***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 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...
