(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Rotational Kinetic Energy

1. The problem statement, all variables and given/known data

A solid cylinder of mass 14.0 kg rolls without slipping on a horizontal surface.

(a) At the instant its center of mass has a speed of 11.0 m/s, determine the translational kinetic energy of its center of mass.

2. Relevant equations

[tex] I_cm = \frac{1}{2}MR^2 [/tex]

[tex]K_R = \frac{1}{2}I\omega^2 [/tex]

3. The attempt at a solution

I can't figure out how to find the moment of inertia without have a radius... any hints?
