Problem
A solid sphere of mass 0.50kg is released from rest at the top of an incline 1.2m above the floor and rolls without slipping to the bottom. Calculate the fraction of the sphere’s total kinetic energy that is rotational when it reaches the bottom. (Moment of inertia of a solid sphere: I=52MR2.)
