Koko fell a distance of 355 feet into an airbag after jumping from the Vegas World Hotel and Casino. The distance d in feet traveled by a freefalling object in t seconds is given by the formula d = 16t 2. To the nearest tenth of a second, how long did the stuntman's freefall last?
:
16t^2 = 355
t^2 = 355%2F16
t = sqrt%2822.1875%29
:
t = 4.71 seconds
