Question

A high-speed flywheel in a motor is spinning at 450 rpm when a power failure rapidly occurs. A flywheel has mass 42.0 kg and diameter 78.0 cm. The power is off for 32.0 s and throughout this time the flywheel slows due to friction in its axle bearings. All through time the power is off, the flywheel makes 160 whole revolutions.

How long after the beginning of power failure would it have taken the flywheel to stop if the power had not come back on?

How numerous revolutions would the wheel have made through this time?
