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 typical modern turbine has blades 56 m long that spin at 13 rpm. at the tip of a blade, what are (a) the speed and (b) the centripetal acceleration?
