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 0.16 m? (b) What is the rotational kinetic energy of the larger cylinder, of radius 0.84 m?
