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

You are in an elevator standing on a scale. The scale reads the normal force that it needs to exert on you (upwards) so you stay on top of it. What would the FBD of you look like if the elevator was accelerating downwards? Show the difference in force through arrow length.
