John,
The formula for calculation the velocity of any object falling in a vacuum 
on this planet is: 32 feet per second squared times the time that the 
object has fallen. To get anything real from this you would have to 
calculate the force in the opposite direction due to air resistance at each 
point in that objects fall and apply that as an acceleration in the 
opposite direction. (Its possible to do this without the use of a computer, 
but to really screw it up righteously you'ld need at least a 286. |-))
