A sphere with a mass of 8kg and diameter of 25cm is initially on top of a ramp at rest with an angle of 30 degrees with a base length of 5 meters. The sphere rolls down the ramp with an initial velocity of 3 m/s.
a) What is the final velocity of the sphere at the bottom of the ramp if the coefficient of friction is 0.3 [I=2/5 mr^2]
b) Calculate the revolutions per second of the sphere from when it leaves the top of the ramp and when it reaches the bottom of the ramp
c) How far does the sphere roll into the grassfield before it comes to the stop if the grassfield has a coefficient of friction of 0.6?

A pool ball is released from rest at the top of a 1m high ramp. The ramp makes an angle of 34 degrees with the horizontal. The pool ball rolls to the bottom of the ramp and then smoothly continues to roll up the adjacent ramp that is .5m high and makes an angle of 12 degrees with the horizontal. Calculate the velocity of the pool ball as it reaches the very end of the 12 degree ramp.

A car (initially at rest) slides down a smooth, 30 m long ramp (neglect friction on the ramp) that is inclined at 6 deg. from the horizontal. At the bottom of the ramp, this car hits a second, identical car that is also initially at rest on a horizontal road. The effective coefficient of friction for the cars on the road is 0.6. How far will the cars roll after the crash before stopping?
