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 turn between t=0 and the time it stopped? b) when did it stop? c) what was its acceleration as it slowed down? I tried the problem but I am doubting my answers. for a) i got a really big answer :S b)12 sec c)-8.2 rad/s2 Can someone help me solve these problems please?
