... In a crash test, an automobile of mass 1500kg collides with a wall. The initial and final velocities of the automobile are vi= -15.0i m/s and vf=2.60i m/s. If the collision lasts for 0.150 seconds, what would be the impulse caused by the collision and the average force exerted on the automobile? Let ...

Momentum!!!
... If no net force or net impulse acts on a system, the momentum of that system cannot change. When momentum, or any quantity does not change, we say it is conserved. Law of Conservation of Momentum In the absence of an external force, the momentum of a system remains unchanged. ...
