An automobile of mass 1500Kg moving at 25.0 m/s collides with a truck of mass 4500 kg at rest. The bumpers of the two vehicles lock together during the crash. Compare the force exerted by the car on the truck with that of the truck on the car during the collision. Is one force larger than the other or are they equal in magnitude to each other? What is the final velocity of the car and truck just after the collision?
