a paratrooper survived a training jump from 1200 ft when his parachute failed to open but provided some resistance by flapping in the wind. Allegedly he hit the ground at 100 mi/h after falling for 10 seconds. you should first find the drag coefficient gamma, assuming a terminal velocity of 100 mi/h and also that the deceleration of the paratrooper due to air resistence is proportional to his velocity, with constant of proportionality gamma. gamma=? Next find the distance D fallen in 10 seconds. D=?
