Amy is trying to knock off an object that's placed on a pedestal by throwing a ball at it. She has two options: one ball that's made of putty which sticks to the object and the other ball that's made off rubber which bounces after hitting the object. Using the free body diagram (attached), please answer the following questions: Which ball is more effective at knocking off the object if both balls have the same mass and same velocity impact? If both balls have a mass of 0.03 kg and a speed of 3.0 m/s, what is the change in momentum of the putty ball? If the collision lasts 0.003s, what is the force on the object? If the rubber ball rebounds with a speed of 3.0 m/s in the opposite direction, what is its change in momentum? if the rubber ball's collision lasts 0.003s, what is the force on the object?

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?”
