9.16 " At I = 0 a grinding wheel has an angular velocity of 24.0 rad/s. It has a constant angular acceleration of 30.0 rad/s? 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 accel- eration. (a) Through what total angle did the wheel turn between 0 and the time it stopped? (b) At what time did it stop? (c) What was its acceleration as it slowed down? 1
