At time t=0 a grinding wheel has an angular velocity of 20.0 rad/s . It has a constant angular acceleration of 30.0 rad/s2 until a circuit breaker trips at time t = 1.90 s . From then on, the wheel turns through an angle of 440 rad as it coasts to a stop at constant angular deceleration. A. Through what total angle did the wheel turn between t=0 and the time it stopped? B. At what time does the wheel...
