Question

At t=0 a grinding wheel has an angular velocity of 30.0 rad/s . It has a constant angular acceleration of 35.0 rad/s2 until a circuit breaker trips at time t = 1.60 s . From then on, it turns through an angle 434 rad as it coasts to a stop at constant angular acceleration.

Answer 1

Explanation:

It Has A Constant Angular Acceleration Of 35.0 Rad/s^2 Until A Circuit Breaker Trips At Time T= 2.50 S. From Then On, The Wheel Turns ...............
