A uniform hollow spherical ball of mass 1.75 kg and radius 40.0 cm is rolling up a ramp that rises at 30.0° above the horizontal. Speed of the ball at the base of the ramp is 8.20 m/s. Moment of inertia of hollow sphere is given by I=(2/3)m r2. (a) What is the angular velocity of the ball at the base of the ramp? (b) Determine how far up the ramp does it roll before it starts to roll downward. Assume rolling takes place without slipping.

A hollow sphere (mass 8.8 kg, radius 54.8 cm) is rolling without slipping along a horizontal surface, so its center of mass is moving at speed vo. It now comes to an incline that makes an angle 56o with the horizontal, and it rolls without slipping up the incline until it comes to a complete stop. Find a, the magnitude of the linear acceleration of the ball as it travels up the incline, in m/s2.
