At t=0 a grinding wheel has an angular velocity of 30.0 rad/s . It has a constant angular acceleration of 35.0 rad/s2 until a circuit breaker trips at time t = 1.90 s . From then on, it turns through an angle 440 rad as it coasts to a stop at constant angular acceleration.

Q1: Through what total angle did the wheel turn between t=0 and the time it stopped?

Q2: At what time did it stop?

Q3: What was its acceleration as it slowed down?
