Question 108997
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 = {{{355/16}}}
t = {{{sqrt(22.1875)}}}
:
t = 4.71 seconds
