When the 0.9-lb box kite shown in Fig. P9.73 is flown in a 20-ft/s wind, the tension in the string, which is at a 30° angle relative to the ground, is 3.0 lb. (a) Determine the lift and drag coefficients for the kite based on the frontal area of 6.0 ft2. (b) If the wind speed increased to 30 ft/s, would the kite rise or fall? That is, would the 30° angle shown in the figure increase or decrease? Assume the lift and drag coefficients remain the same. Support your answer with appropriate calculations.
