flywheel in a motor is spinning at 570.0 rpm when a power failure suddenly occurs. The flywheel has mass 40.0 kg and diameter 75.0 cm. The power is off for 33.0 ss, and during this time the flywheel slows down uniformly due to friction in its axle bearings. During the time the power is off, the flywheel makes 220.0 complete revolutions.

A flywheel in a motor is spinning at 570.0 rpm when a power failure suddenly occurs. The flywheel has mass 40.0 kg and diameter 75.0 cm. The power is off for 33.0 ss, and during this time the flywheel slows down uniformly due to friction in its axle bearings. During the time the power is off, the flywheel makes 220.0 complete revolutions.
At what rate is the flywheel spinning when the power comes back on?
Express your answer in revolutions per minutes.
