Chapter 9, Problem 9.86(choose chapter or problem)
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 mass 1000 kg and diameter 1.80 m; its top angular speed was (a) At this angular speed, what is the kinetic energy of the flywheel? (b) If the average power required to operate the bus is how long could it operate between stops?
