At time t=0 a grinding wheel has an angular velocity of 26.0 rad/s . It has a constant angular acceleration of 33.0 rad/s2 until a circuit breaker trips at time t = 2.40 s . From then on, the wheel turns through an angle of 431 rad as it coasts to a stop at constant angular deceleration.

A) At what time does the wheel stop?

B) What was the wheel's angular acceleration as it slowed down?
