2. A 10-kg box of books is initially at rest on a horizontal surface. A horizontal force of 60.0 N is required to set the box in motion and a horizontal force of 50 N is required to keep the block moving with constant speed. What will be the acceleration of the box if a force of 60.0 N is constantly applied after it moves?

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?”
