Problem

Consider a solid sphere of radius R and mass M rolling without slipping. At any instant during the motion, which form of kinetic energy is larger, translational or rotational? 

A) Rotational kinetic energy is larger.

B) Translational kinetic energy is larger.

C) Both are equal.

D) You need to know the speed of the sphere to tell.

E) You need to know the acceleration of the sphere to tell.
