On a snowy morning, a fast car skids along the road and runs into the back end of a truck. The bumpers of the car and truck stick together in the collision and the car and truck slide forward slowly after they hit. Describe this collision by explaining the following: What type of collision is this (elastic or inelastic) and how do you know?
What happens to the momentum of each vehicle in this collision?
Does this collision obey the law of conservation of momentum?
