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 of0.190 rad/s2. After making 2840 revolutions, its angular speed is 138 rad/s.
(a) What is the initial angular velocity of the turbine?
rad/s
(b) How much time elapses while the turbine is speeding up?
s
