Question

A wind turbine is initially spinning at a constant angular speed.As the wind's strength gradually increases, the turbine experiencesa constant angular acceleration of 0.120rad/s2. After making 2871revolutions, its angular speed is 138rad/s. (a) What is the initial angular velocity of theturbine?

1 rad/s

(b) How much time elapses while the turbine is speeding up?

2 s

Thanks for your help! :) have a great weekend!

Explanation / Answer

Angular acceleration  = 0.12 rad /s^ 2

Angular displacement = 2871 rev = 2871 * 2(pi)rad

Final angular speed w ‘ = 138 rad / s
