2. (10 pts. total) A small wind turbine has blades that rotate counterclockwise with point P located at the tip of one of the blades at the 3 o'clock position at time t = 0 seconds. The graph P below represents the height of point P (in feet) at time t seconds. Use the graph to find each of the following. (a) (1 pt.) How long does it take a blade to make one full rotation? 8 sec 140 TP-fit) feet 130 (b) (2 pts.) What is the distance from the ground to 120 110 the center of the rotating blades? 100 . 90 90 F+ . 80 - 70 . 60 . 50 . 40 (c) (2 pts.) How long is each blade? . 30 . 20 50 Ft 10 . I seconds 8 12 16 (d) (5 pts.) Write a formula in the form y = Asin(Bt) + k or y = Acos(Bt) + k for the height of point P at time t seconds after the blades start rotating
