Translational and Rotational Movements

A passenger bus in Zurich, Switzerland derived its motive power from the energy stored in a large flywheel. The wheel was brought up to speed periodically, when the bus stopped at a station, by an electric motor, which could then be attached to the electric power lines. The flywheel was a solid cylinder with a mass of m and a diameter of d; its top angular speed was omega (w) .

1. At this angular speed, what is the kinetic energy of the flywheel?

2. If the average power required to operate the bus is P, how long could it operate between stops?
