A penny was dropped from a window

Question

A penny was dropped from the window of a building, 64 feet above the ground. Write an equation for the height of the penny, h, at the time t seconds after it was dropped.

Answer 1

x(t) = x(0) - v(0)t + .5a(t^2)

 

initial height = 64 ft

initial velocity = 0 ft/s

acceleration = -32.17 ft/s^2 (downward)

 

h = 64 - .5(32.2)(t^2)
