Q. At t = 0 a grinding wheel has an angular velocity of 23.0 rad/s. It has a constant angular acceleration of 31.0 rad/s2 until a circuit breaker trips at t = 2.00 s. From then on, it turns through 432 rad as it coasts to a stop at constant angular acceleration.

Q. A car with a mass of 1.50 x 10^3kg starts from rest and accelerates to a speed of 18.0 m/s in 12.0s. Assume that the force of resistance remains constant at 400.0 N during this time. What is the average power developed by the car's engine?
