A solid sphere of weight 8.00 lb rolls up an incline with aninclination angle of 30.0 degrees. At the bottom of theincline the center of mass of the sphere has a translationalspeed of 16.0 ft/s.
a.) What is the kinetic energy of the sphere at the bottom ofthe incline?
b.) How far does the sphere travel up the incline?
c.) Does the answer to b.) depend on the weight of thesphere?
