Algebra

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

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

  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
