How do I calculate the impact force of a moving object colliding with a stationary object from the depth of impact of the moving object into the stationary object?
To clarify, I have a large malleable stationary object and a smaller solid moving object, and need to find out the impact force between the two objects after collision by measuring the distance the smaller object has penetrated into the larger object.
I know the initial speed prior to impact, and the final velocity is zero, as well as the malleability of the stationary object and the duration of the deceleration.
Thanks in advance

You can assume the stationary object as a spring with the spring constant k to model the force,
then the force will depends on the displacement\vec{x}, i.e.  \vec{F}=-k \vec{x}.
