An object is dropped from a bridge. Find the distance the object has fallen when its speed reaches 132 ft/s. Use the equation

Question

v =

64d
,
where v is the speed in feet per second and d is the distance in feet.

Answer 1

the drop time is
... t = 132 ft/s / 32 ft/s²

it starts from rest, so the average velocity is ... (0 + 132) / 2 ft/s

the distance is
... d = drop time * average velocity
