There was once a time when Aikins never even considered jumping without a parachute. This is the speed at which the drag from air resistance exactly balances the force of gravity pulling him down. Answer (1 of 4): If she is at terminal velocity, she is no longer accelerating and so her weight is fully supported, ie, matched, by the upward force of air resistance. v = 174(1 - 0.834t) C When she accelerates, the resultant force on her is zero. Question 1002200: When a skydiver jumps from an airplane, her downward velocity, in feet per second, before she opens her parachute is given by the formula below, where t is the number of seconds that have elapsed since she jumped from the airplane. After opening parachute, she falls at a much smaller A skydiver is falling at terminal velocity before opening her parachute. This value differed significantly from the others.
