Question: At t=0 a grinding wheel has an angular velocity of 30.0rad/s . It has a constant angular acceleration of 27.0rad/s^2 until a circuit breaker trips at time t = 1.60s . From then on, it turns through an angle 433rad 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?
