The angular momentum of a flywheel having a rotational inertia of 0.140 kg m2 about its axis decreases from 3.40 to 0.90 kg m2/s in 2.20 s. What is the average torque acting on the flywheel about its central axis during this period? Assuming a uniform angular acceleration, through what angle will the flywheel have turned?(rad) How much work was done on the wheel? What is the average power of the flywheel?
