At t=0t=0 a grinding wheel has an angular velocity of 27.0 rad/srad/s . It has a constant angular acceleration of 30.0 rad/s2rad/s2 until a circuit breaker trips at time ttt = 2.40 ss . From then on, it turns through an angle 438 radrad as it coasts to a stop at constant angular acceleration. Part APart complete Through what total angle did the wheel turn between t=0t=0 and the time it stopped? θθ = 589 radrad SubmitPrevious Answers Correct Part B At what time did it stop? tt = 12.5 ss SubmitPrevious AnswersRequest Answer Incorrect; Try Again; 3 attempts remaining Part C What was its acceleration as it slowed down?
