A car is designed to get its energy from a rotating flywheel in the shape of a uniform, solid disk of radius 0.700 m and mass 600 kg. Before a trip, the flywheel is attached to an electric motor, which brings the flywheel's rotational speed up to 4.90 ✕ 103 rev/min.   (a) Find the kinetic energy stored in the flywheel (in J). J (b) If the flywheel is to supply energy to the car as a 11.5 hp motor would, find the length of time in hours the car could run before the flywheel would have to be brought back up to speed. h
