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 1070 kg and a diameter of 1.70 m; its top angular speed was 2970 rev/min . 1. At this angular speed, what is the kinetic energy of the flywheel? 2. If the average power required to operate the bus is 1.89×10^4 , how long could it operate between stops?
