At t = 0 a grinding wheel has an angular velocity of 24.0 rad/s. It has a constant angular acceleration of 30.0rad/s230.0rad/s2 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 time it stopped? b) At what time did it stop?
c) What was its acceleration as it slowed down?
