A wind turbine is originally spinning at a constant angular speed. As the wind's strength gradually increases, the turbine experiences a constant angular acceleration of 0.120rad/s2. After making 2871revolutions, its angular speed is 138rad/s.

1. What is the initial angular velocity of the turbine?

 

2. How much time elapses as the turbine is speeding up?
