There exists a 0.35 m radius turntable that has a constant angular acceleration of 0.145 rad/s2 from rest. How many times does this turntable rotate in 12 seconds after the acceleration begins? After the acceleration begins, how long does it take for the magnitude of the acceleration of a point on the rim of the turntable to reach 0.12 m/s2?

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 0.168 rad/s2. After making 2870 revolutions, its angular speed is 146 rad/s. (a) What is the initial angular velocity of the turbine? (b) How much time elapses while the turbine is speeding up?
