**MathMate**, Monday, December 5, 2011 at 4:43pmYou have enough information, but not enough equations.

A free-falling object starting from rest accelerates (assuming no air resistance) and the distance from the starting point is given by:

x=-(1/2)gt²

where

x = distance from starting point, positive upwards

g = acceleration due to gravity, 32.2 ft/s², or 9.81 m/s², depending on the unit you use.

t = elapsed time in seconds since the beginning of the free fall.

For the first part, the velocity, v, after time t is given by:

v = -gt

again velocity is positive upwards.
