A wind turbine is initially spinning at a constant angular speed.As wing strength gradually increases, the turbine experiences aconstant angular acceleration of 0.160 rad/s^2. After moving 2821revolutions, angular speed is 135 rad/s

A) What was the initial angular velocity of the turbine (inrad/s)?

B) What was the time elapsed while the turbine is speeding up(in seconds)?
