Question: As a result of friction, the angular speed of a wheel changes with time according to where 0 and / are constants. The angular speed

As a result of friction, the angular speed of a wheel changes with time according to where ώ0 and / are constants.
The angular speed changes from 3.50 rad/s at t = 0 to 2.00 rad/s at t = 9.30 s. Use this information to determine / and ώ0. Then determine
(a) The magnitude of the angular acceleration at t = 3.00 s,
(b) The number of revolutions the wheel makes in the first 2.50 s, and
(c) The number of revolutions it makes before coming to rest.
