You are a fitness trainer developing an exercise that involves pulling a heavy crate across a rough surface. You attach a rope to a crate of mass ?=45.0 kg and place it on a carpeted track. Using your physics expertise, you have already determined that the coefficient of kinetic friction between the crate and the carpet is ?k=0.470.   To test the apparatus, you have one of your employees pull on the rope as hard as she can. If she pulls with a force of ?=315 N along the direction of the rope, while the rope makes an angle of ?=23.0° with the floor,what is the acceleration ? of the box? Use ?=9.80 m/s2.

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?”
