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

A 74.2 kg person is standing inside an elevator. The elevator is moving upward at 2.98 m/s and is decreasing speed at a rate of 1.18 m/s^2. What is the net force that is acting on the person?
