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?”

A large block is being pushed against a smaller block such that the smaller block remains elevated while being pushed. The mass of the smaller block is m=0.45 kg.
