Modern wind turbines are larger than they appear, and despite their apparently lazy motion, the speed of the blades tips can be quite high-many times higher than the wind speed. A turbine has blades 55 m long that spin at 13 rpm . At the tip of a blade, what is the speed? At the tip of a blade, what is the centripetal acceleration?
