At t = 0 a grinding wheel has an angular velocity of 31.0 . It has a constant angular acceleration of 28.0 until a circuit breaker trips at 1.50 . From then on it turns through 352 as it coasts to a stop at constant acceleration. (There are several ways to do this question, and there is no preferred order in which to do A, B and C.)

A)At what time (measured from t = 0) did the grinding wheel stop?

B)What was the angular acceleration of the grinding wheel as it slowed down?

C)Through what total angle did the wheel turn between t = 0 and the time it stopped?
