A wind turbine is initially spinning at constant angular speed. As the wind's strength gradually increases, the turbine experiences a fix angular acceleration of 0.160 rad/s2. After making 2812 revolutions, its angular speed is139 rad/s.
(a) Evaluate the initial angular velocity of the turbine?
rad/s
(b) Evaluate how much time elapses while the turbine is speeding up?
s
