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 standing on a train which begins to accelerate away at 4.50 m/s. If you
have a mass of 70 kg, what is the minimum force of friction required between your
feet and the train so that you do not slide backwards relative to the train?
