Question: A simple wheel has the form of a solid cylinder of radius r with a mass m uniformly distributed throughout its volume. The wheel is pivoted on a stationary axle through the axis of the cylinder and rotates about the axle at a constant angular speed. The wheel rotates n full revolutions in a time interval t. What is the kinetic energy K of the rotating wheel? Answer in terms of m, r, n, t, and pi.
