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 1090kg and a diameter of 1.90m ; its top angular speed was 2950rev/min .
Part A
At this angular speed, what is the kinetic energy of the flywheel?
Part B
If the average power required to operate the bus is 1.85
