A 1.99 kg solid sphere (radius = 0.104 m) is released from rest at the top of a ramp and allowed to roll without slipping. The ramp is 0.795 m high and 4.97 m long. When the sphere reaches the bottom of the ramp, what is its total kinetic energy? What is its rotational kinetic energy? What is its translational kinetic energy?
