The skydiver again: When a skydiver jumps from an airplane, her downward velocity, in feet per second, before she opens her parachute is given by v = 176(1 − 0.834t ), where t is the number of seconds that have elapsed since she jumped from the airplane. We found earlier that the terminal velocity for the skydiver is 176 feet per second. How long does it take to reach 90% of terminal velocity?
