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?
