23. A wind turbine is initially spinning at a constant angular speed. As the wind's strength gradually increases, the turbine experiences a con- stant angular acceleration of 0.140 rad/s. After making 2870 revolutions, its angular speed is 137 rad/s. (a) What is the initial angular velocity of the turbine? (b) How much time elapses while the turbine is speeding up?
