Question 171653: According to the 1998 Guinness Book of World Records stuntman Dan Koko fell a distance of 365 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?

According to the 1998 Guinness Book of World Records stuntman Dan Koko fell a distance of 365 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?
-----------------
d+=+16t%5E2 Ignoring wind resistance and using 32ft/sec/sec as acceleration due to gravity.
365+=+16t%5E2
t%5E2+=+365%2F16
t+=+sqrt%28365%2F16%29
t+=+sqrt%28365%29%2F4
t =~ 4.8 seconds
-------------
His speed at impact was 32t, = 153 ft/sec = 104 mph
