Impact force reduction after passing through a medium

[boyboy400]

TL;DR Summary

A car hits a mass of soil with the impact force of F. We know properties of the mass and its dimension. What is the force felt at the other side of the mass?

Hello,

Please see the attached sketch. A car hits a mass of soil and applies the impact force of F. The force/wave travels the distance L through the mass at the end of which there is a wall so I think the force attenuates. Assume we have all the properties of the mass. My question is, what would be the attenuated/decreased F felt by the wall? I know this can be modeled with FEM but I have a feeling there should be an analytical solution based on physics for it too. Would really appreciate any insight.

Can you say what the context of the question is?

Not sure what you mean by the context. Let's say you want to design the wall to withstand the force but you know the force felt by the wall will be reduced due to existence of the mass of soil.

Why are you anticipating a car running into your wall so that you need to add protection?

This looks like some sort of accident investigation. Please be aware that we can't provide any legal advice in situations like this.
