RI Review Constants At t=0 a grinding wheel has an angular velocity of 29.0 rad/s. It has a constant angular acceleration of 28.0 rad/s² until a circuit breaker trips at time t = 2.50 s From then on, it turns through an angle 438 rad as it coasts to a stop at constant angular acceleration. Part A Through what total angle did the wheel turn between t=0 and the time it stopped? 140 AXD w ? rad Submit Request Answer Part B At what time did it stop? 190 A20 ? 311 S Submit Request Answer Part C What was its acceleration as it slowed down? HO | ΑΣφ ? IIR rad/ Submit Request Answer
