Consider two blocks connected by a string (call this the internal string) and being pulled vertically upward by another string (the external string) attached to block A. Suppose that blocks A and B have masses of 3.0 kg and 2.0 kg, respectively, and suppose that the external string’s tension has a magnitude of 55 N. The internal string’s mass is 100 g. Find the acceleration of the system, the magnitude of the tension force on block B, and the difference in the magnitudes of the tension forces exerted by each end of the string.    The acceleration of the system is ______ m/s2.   The tension force on block B is ____ N.   The difference in the magnitudes of the tension forces exerted by each end of the string is ______ 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?”
