The angular momentum of a flywheel having a rotational inertia of 0.250 kg·m2 about its central axis decreases from 2.80 to 1.800 kg·m2/s in 1.00 s.
(a) What is the magnitude of the average torque acting on the flywheel about its central axis during this period?
N·m
(b) Assuming a uniform angular acceleration, through what angle does the flywheel turn?
rad
(c) How much work is done on the wheel?
J
(d) What is the average power of the flywheel?
W
