Recall #1: The KE due to rotation, of an object whose moment of inertia is I, which is rotating with angular velocity w, is:
(1) KErot = .5 I w^2
Recall #2. The moment of inertia of a uniform cylinder of mass m and radius R is expressed by:
(2) I= .5 m R^2
Recall #3. From equations of linear motion and of angular ...
