At time t=0 a grinding wheel has an angular velocity of 25.0 rad/s. It has a constant angular acceleration of 32.0 rad/s2 until a circuit breaker trips at time t= 1.80 s. From then on, the wheel turns through an angle of 433 rad as it coasts to a stop at constant angular deceleration. What was the wheel's angular acceleration as it slowed down?

A wheel rotates with a constant angular acceleration of 6.0 rad/s². During a certain time interval, its angular displacement is 6.0 rad. At the end of the interval, its angular velocity is 12.0 rad/s. Its angular velocity at the beginning of the interval is O 1.0 rad/s O 12 rad/s O 6.0 rad/s O O rad/s O 8.5 rad/s Save for Later Submit Answer
