Two uniform solid cylinders, each rotating about its central (longitudinal) axis, have the same mass of 1.25 kg, and rotate with the same angular speed of 235 rad/s, but they differ in radius.
(a) What is the rotational kinetic energy of the smaller cylinder, of radius 0.33 m?
J
(b) What is the rotational kinetic energy of the larger cylinder, of radius 0.5 m?
J
