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?”

Question

One or more external forces, large enough to be easily measured, are exerted on each object enclosed in a dashed box shown. Identify the reaction to each of these forces.
