Calculating distance from force and impact

[robwrightham]

If I know the mass of an object, the force of impact, how do i calculate the distance the object is from the impact point?
i have a stationay object of known mass being hit with a piston at a known force and speed can i work backwards and determine at what height if dropped would be equivalent to the known perameters

So you want to know at what height an object would have to be dropped to have the same force imparted to it that a specific piston would?

Hi drakkith, yes that's exactly what I need to calculate, is it possible ? Can you help ?
