By landing properly and on soft ground (and by being lucky!), humans have survived falls from airplanes when, for example, a parachute failed to open, with astonishingly little injury. Without a parachute, a typical human eventually reaches a terminal velocity of about 62 . Suppose the fall is from an airplane 1350 high.
Part A How fast would a person be falling when he reached the ground if there were no air drag?=
Part B If a 60 person reaches the ground traveling at the terminal velocity of 62 , how much mechanical energy was lost during the fall?=
Part C What happened to that energy?
