According to a newspaper account, a paratrooper survived a training jump from 1250 ft when his parachute failed to open but provided some resistance by flapping in the wind. Allegedly he hit the ground at 104 mi/h after falling for 8.5 seconds. To test the accuracy of this account, you should first find the drag coefficient ,p , assuming a terminal velocity of 104 mi/h and also that the resistance of the paratrooper falling through the air is proportional to his velocity.

Remember that the accleration due to gravity near the earth's surface is 32 ft/sec2.

P=?
Next, find the distance D fallen in 8.5 seconds.
