An object is dropped from a bridge. Find the distance the object has fallen when its speed reaches 104 ft/s.
Use the equation v = 8sqrt(d), where v is the speed of the object and d is the distance.
~~~~~~~~~~~~~~~~~~~~~~~~~ 

Do as they instructed you.


v = 8%2Asqrt%28d%29,

104 = 8%2Asqrt%28d%29,

104%2F8 = sqrt%28d%29,

sqrt%28d%29 = 13,

d = 13%5E2 = 169.

Answer.  d = 169 ft.
