Formula for collision between car and animal/human

[Noobert]

I have been searching for formulas to do with car crashes. I have found formulas on the force that a car crash exerts on the body of a person driving the car but I cannot find any to do with a collision or crash between a car and a human / animal. I need an equation so I can compare the difference between the force exerted and possible damage to a person being hit by a bull bar as apposed to a car with no bull bar and crumple zones.

Any information will be a big help! I think I might be able to use a Elastic collision equation but I'm not sure. In the meantime i'll keep searching.

Unfortunately, there is no one single equation or formula to accurately describe the forces and possible damages from a car crash involving a human or animal. The best way to compare the difference between the force exerted and potential damage caused by a bull bar versus a car with no bull bar and crumple zones is to use a combination of equations and data from real-world crashes. For instance, you could use the elastic collision equation to estimate the initial energy and momentum of the two objects at the start of the collision and then use data from real-world crashes to estimate how much energy and momentum is lost due to the crumple zones. You could also use data from real-world crashes to estimate the difference in force and potential damage between cars with and without bull bars.
