a paraTROOPER JUMPS FROM A PLANE.HOW MANEY FEET WILL HE FALL BEFORE HE REACHES TERMINAL VOLICITY.AND WHAT SPEED WILL IT BE IF HE WEIGHS 175 LBS.
Before or after his parachute opens? There are different terminal velocities before and after.
You need a drag coefficient and frontal area for the person jumping These will depend upon his body-mass index and how he orients his body in the flow (belly first or head first). Only an approximate answer can be provided.
