Jemma is outside with a basketball that has a mass 0.590 kg and a radius of 0.120 m. the ball can be treated as a hollow sphere (I=2MR2/5). A. Calculate the linear velocity of the sphere if it is pushed down a ramp that is 5.00 m long and makes an angle of 20.0o to the horizontal. Assume that the ball starts from rest. B. Calculate the angular velocity at the bottom of the ramp.\
