car is designed to get its energy from a rotating flywheel (solid disk) with a radius of 1.00 m and a mass of 475 kg. Before a trip, the flywheel is attached to an electric motor, which brings the flywheel's tational speed up to 5000 rev/min. (a) Find the kinetic energy stored in the flywheel. (b) If the flywheel is to supply energy to the car as would a 10.0-hp motor, find the length of time the car could run before the flywheel would have to be brought back up to speed.
