when a skydiver jumps from an airplane, the distance of d in feet the diver falls in t seconds before opening the parachute is given by the formula d=16t^2 (the formula asumes that there is no air resistance) find the time it takes a skydiver to fall 1,296ft before openening the parachute.

Answer 1

1296 = 16 t^2

Divide both sides by 16.

81 = t^2

Get square root of both sides.
