A solid sphere of radius(adsbygoogle = window.adsbygoogle || []).push({}); 0.100mand mass14.3kgrolls without slipping up a surface inclined at30 degreesto the horizontal. At a certain initial position the sphere's total kinetic energy is90.1J.

(a) How much of this initial kinetic energy is rational?

(b) What is the speed of the center of mass of the sphere at the initial position?

After the sphere has moved1.00mup along the incline from its initial position:

(c) What is its total kinetic energy?

(d) What is the speed of its center of mass?
