According to the Guinness Book of World Records, 1998, stuntman Dan Koko fell a distance of 312 feet into an airbag after jumping from the Vegas World Hotel and Casino. The distance d in feet traveled by a free-falling object in t seconds is given by the formula d = 16t2. To the nearest tenth of a second, how long did the fall last?

Respuesta :

Answer:

t = 4.4 second

Explanation:

Given :

Distance = 312 feet

time = t second

Distance is given by the formula, d = 16[tex]t^{2}[/tex]

Therefore, 312 = 16[tex]t^{2}[/tex]

312/16 = [tex]t^{2}[/tex]

19.5 =  [tex]t^{2}[/tex]

t = [tex]\sqrt{19.5}[/tex]

t = 4.4 second
