Two Cars in 2-Dimensional Collision

Inelastic Collision :  Collisions among objects are governed through laws of momentum and energy. While a collision occurs within an isolated system, the whole momentum of the system of objects is conserved. Given that there are no net external forces acting upon the objects, the momentum of all objects before the collision equals the momentum of all objects after the collision. If there are just two objects included within the collision, then the momentum modify of the person objects are equal within magnitude and opposite within direction.
