Acar is designed to get its energy from a rotating flywheel in the shape of a uniform, solid disk of radius 0.600 m and mass 540 kg. before a trip, the flywheel is attached to an electric motor, which brings the flywheel's rotational speed up to 5.10 ✕ 103 rev/min.
(a) find the kinetic energy stored in the flywheel.
