... 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 ...
