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 0.111 rad/s^{2}. After making 2870 revolutions, its angular speed is 131 rad/s. **(a)** What is the initial angular velocity of the turbine? **(b)** How much time elapses while the turbine is speeding up?

Step 1

Consider the initial angular speed of the turbine be *ω _{0}*, the final angular speed of the turbine be

The given values are,

Step 2

**(a)**

Write the equation of angular motion, and solve for the...
