A high-speed flywheel in a motor is spinning at 500 rpmrpm when a power failure suddenly occurs. The flywheel has mass 35.0 kgkg and diameter 75.0 çmcm, The power is off for 30.0 ss, and during this time the flywheel slows due to friction in its axle bearings. During the time the power is off, the flywheel makes 160 complete revolutions. a) At what rate is the flywheel spinning when the power comes back on? Express your answer in radians per second. b) 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? Express your answer in seconds. c) How many revolutions would the wheel have made during this time? Express your answer in revolutions.
