A wind turbine is initially spinning at a constant angular speed. As the wind's strength gradually increases, the turbine experiences a constant angular acceleration of 0.120 rad/s2. After making 2876 revolutions, its angular speed is 139 rad/s.

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

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