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?”

Part A
How does a rocket take off? What is the upward force on it?
O The rocket forces the exhaust gases down, and the hot gases push up on the rocket. The two forces are a Newton's second-law pair. The rocket accelerates upward because the force of the exhaust gases on the rocket is greater than the force of gravity.
