Energy from vehicular impacts?

[Imaginym]

If something gets hit by a car or a truck or something.... Well, we can find the Kinetic Energy, right? 0.5 * Mass * Velocity^2 as far as I know.

But what about when you want to know how much energy something received as a result of that vehicular impact?

Most things don't have the shape of a vehicle, for one. And speaking personally, I don't know HOW you would apply the force from the vehicular collision onto the object the vehicle hit.

How do I determine such information? Apologies for any bother.

Firstly, we're gonna have to find out how the final crash ends.

If it ends up with the car and the victim crashing into a wall, then the full KE of the car is used as dura. Otherwise, in case the guy is sent flying, we use the momentum formula to figure out the speed. This is what Kaltias told me.

We'll also have to take into account whether the guy braces or not.
