Car Collision response - small collision

When 2 car collide, as soon as I detect collision occurs, my code compute:

1, result velocity of both cars, using elastic collision equation

2, solve the penetration along the normal of collision

Result is okay. Only I see the car been collided moves small distance, but I need bigger one (like the game Asphat by gameloft, if you crash a npc car, that car moves far forward at the collision time), any suggestion?

Fattie,

The only reason is I want to build the wheel from scratch since I want to know the trick behind physics engine.

bompi88,

Thanks, it’s a good point. I’ll try. Just still want to know what most of the car game do in such a situation.
