Question: A solid sphere of weight 36.0 N rolls up an incline at an angle of 30.0°. At the bottom of the incline the center of mass of the sphere has a translational speed of 4.90 m/s.
(a) What is the kinetic energy of the sphere at the bottom of the incline?
(b) How far does the sphere travel up along the incline?
(c) Does the answer to (b) depend on the sphere's mass?
