The angularmomentum of a flywheel having a rotational inertia of 0.100 kgm2 aboutits central axis decreases from 3.40to 1.800 kgm2/s in0.90 s.
(a) What is the magnitude of the average torque acting on theflywheel about its central axis during this period?
(b) Assuming a uniform angular acceleration, through what angledoes the flywheel turn?
(c) How much work is done on the wheel?
(d) What is the average power of the flywheel?
