Explain how each of Newton's laws of motion (1-3) relate to the following description: A light car slides on Ice and runs into a parked truck. The collision causes the car to slow down and the truck to start moving. The change in the car's speed was greater than the change in the truck's speed. Select the two statements that best describe how specific laws of motion relate to the description of the collision Your answer: 1st Law: The car is still moving in the same direction after the collision 1st Law: The truck does not start moving until the car exerts a force on it. 1st Law: The car changes speed more because it was moving first. 2nd Law: The car has a greater change in speed because it has less mass. 2nd Law: The car has a greater change in speed because the truck pushes harder, 2nd Law: The damage to each vehicle will depend on the materials they are made from.

Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”
