Pictured is a car towing a trailer using a regular rope rather than the more common (and sensible) trailer hitch. When discussing a particular body, the action forces are defined as those forces that directly affect the acceleration of that body. With this in mind, classify the forces acting on each object according to whether they are action forces or reaction forces. To simplify matters, ignore the friction acting on the front tires of the car. Be sure to answer both parts of the question.

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?”
