Att -0 a grinding wheel has an angular velocity of 26.0 rad/s. It has a constant angular acceleration of 25.0 rad/s until a circuit breaker trips at time t = 1.70 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? Express your answer in...

At time t=0 a grinding wheel has an angular velocity of 22.0 rad/s . It has a constant angular acceleration of 29.0 rad/s2 until a circuit breaker trips at time t = 2.10 s . From then on, the wheel turns through an angle of 436 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? Express your answer in radians. (b) At...

3. At t-0, angular velocity of a wheel is 24 rad/s, and its angular acceleration is 30 rad/s. (i) How much angle does the wheel turn through after 2 seconds of rotation? (ii) At t-2 sec., the wheel suddenly begins to undergo angular deceleration (negative angular acceleration) of 8.16 rad/s'. What additional time from t -2 secs, does it take the wheel to come to a stop? Hint: Use appropriate rotational kinematic equation to answer different parts of the question....
