The angular momentum of a flywheel having a rotational inertia of 0.983 kg-m2 about its central axis decreases from 3.40 to 0.970 kg-m²/s in 1.70 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 magnitude of the average power done on the flywheel?
