A white penny is dropped off a tall cliff if the penny is in the air for 32 sec how high is the cliff

Answer 1

Assuming no air resistance, the formula is:

$height=(1/2)g{t}^2$

1. g = acceleration due to gravity = 9.8 m/s/s
2. t = time = 32 sec

Plug in the numbers and compute the answer. The height is in meters.
