The angular momentum of a flywheel having a rotational inertia of 0.140 kg ·m2 about its central axis decreases from 3.00 to 0.800 kg ·m2/s in 1.50 s.
(a) what is the magnitude of the average torque acting on the flywheel about its central axis during this period?
(b) assuming a constant angular acceleration, through what angle does the flywheel turn?
(c) how much work is done on the wheel?
(d) what is the average power of the flywheel?
