A high-speed flywheel in a motor is spinning at 500 when a power failure suddenly occurs. The flywheel has mass 37.0 and diameter 79.0 . The power is off for 30.0 and during this time the flywheel slows due to friction in its axle bearings. During the time the power is off, the flywheel makes 180 complete revolutions.

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

How many revolutions would the wheel have made during this time?
