A flywheel in the shape of a solid cylinder of radius 0.801 m and mass 14 kg can be brought to an angular speed of 7.37 rad/s in 0.554 s by a motor exerting a constant torque. After the motor is turned off, the flywheel makes 25.1 rev before coming to rest because of friction (assumed constant during rotation). What percentage of the power generated by the motor is used to overcome friction?
