The blades on the wind turbine are turning with an angular speed of ωo = 30 rpm in the clockwise direction. If the blade length is L = 36.6 m and they are given a constant angular acceleration of α= 0.2 rad/s2 in the clockwise direction, determine: (a) the angular velocity and (b) the magnitude of the acceleration of point A on the tip of the blade when t = 3 minutes.

14. A giant wind turbine generates electrical power with three blades with a diameter of 145 m, and are designed to run safely when the outer end of a blade is moving at around 10 m/s. a. The wind turbine is allowed to begin spinning from rest up to its maximum safe speed over the course of 150 seconds. If this happens at a uniform rate, what is the angular acceleration of the blades, in radians per second? b. After...
