Hi.. im trying to create a car crash simulation. what i want to do is to simulate two cars crashing and calculate the damage that was induced on both cars with the given speed, mass etc. part 2 of that simulation is an enhancement on car A. I would put beams on the doors of the cars to lessen the damage that will result in the crash with the same values for speed, mass etc. I know for a fact that Momentum is the physics behind this things. My problem is I don't know how to calculate the damage induced on both cars and the physical effect of the enhancement i made on car A. How will i Mathematicaly put that enhancement on car A. Any Ideas? hope someone can help me.
