I wonder how could I calculate impact force of an object (eg. a stone) in a free fall impacting on the perfectly inelastic (perfectly hard) floor.(adsbygoogle = window.adsbygoogle || []).push({});

I know:

- m -mass of the falling object

- h -height of the fall

- v -speed at the time of impact

- t -time it takes from highest point to the lowest

- I can also calculate kinetic energy of an object at the impact point

I DO NOT know dwell time (how long the object and the floor are in contact).

So I cannot calculate the impact force with F = \delta p * \delta t.

How can I calculate the impact force?
