A uniform spool is suspended from a vertical wall by a string attached to the spool’s thin axle. The axle is horizontal, as shown below.   The wall is smooth, so it exerts no frictional force on the spool. The tension in the string is 2.6 N.

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?”
