How much energy is stored in the flywheels motion

Reference no: EM13660741

A car is designed to get its energy from a rotating flywheel by a radius of 1.50 m and a mass of 400kg. Before a trip, the flywheel is attached to an electric motor, which brings the flywheel's rotational speed up to 5000 rev/min. How much energy is stored in the flywheel's motion? (I = 1/2 MR2 )

A) 2.25x10^7 J B) 6.17x10^7 J C) 5.26x10^7 J D) 12.4x10^7J
