    What Time Does the Wheel Come to a Stop?

    At t=0 at grinding wheel has an angular velocity of 24.0 rad/s. It has a constant angular acceleration of 30.0 rad/ s2 until circuit breaker trips at t=2.00s. From then on, it turns through 432 rad as ut coasts to a stop at constant angular acceleration. a) through what total angle did the wheel...
