The angular momentum of a flywheel having a rotational inertia of 0.200 kg·m2 about its axis decreases from 3.00 to 1.800 kg·m2/s in 1.80 s.
(a) What is the average torque acting on the flywheel about its central axis during this period?
N·m
(b) Assuming a uniform angular acceleration, through what angle will the flywheel have turned?
rad
(c) How much work was done on the wheel?
J
(d) What is the average power of the flywheel?
W
Basically, all i need is how to find the initial angular velocity for part b. The rest of the variables i have solved for.
