The angular momentumof a flywheel having a rotational inertia of 0.150 kgm2 aboutits central axis decreases from 4.00to 1.400 kgm2/s in1.60 s.
(a) What is the magnitude of the average torque actingon the flywheel about its central axis during this period?
Nm
(b) Assuming a uniform angular acceleration, through what angledoes the flywheel turn?
rad
(c) How much work is done on the wheel?
J
(d) What is the average power of the flywheel?
W
