At t = 0 a grinding wheel has an angular velocity of 24.0 rad/s. It has a constant angular acceleration of 30.0 rad/s3 until a circuit breaker trips at t = 2.00 s. From then on, it turns through 432 rad as it coasts to a stop at constant angular acceleration.
(a) Through what total angle did the wheel turn between t = 0 and the lime it stopped?
(b) At what time did it stop?
(c) What was its acce1era1ion as it slowed down?
