A flywheel in a motor is spinning at 540.0 rpm when a powerfailure suddenly occurs. The flywheel has mass 40.0 kg and diameter75.0 cm. The power is off for 36.0 s, and during this time theflywheel slows down uniformly due to friction in its axle bearings.During the time the power is off, the flywheel makes 230.0 completerevolutions.
1. At what rate is the flywheel spinning when the power comesback on?
2. How long after the beginning of the power failure would ithave taken the flywheel to stop if the power had not come backon?
Express your answer in seconds.
3. How many revolutions would the wheel have made during thistime?
