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

2. In the system shown in the Figure, a force exerted at 37° on the 8.00-kg object. The horizontal surface

A. For what values of F, the system will stay at rest?
B. For what values of F does the m2 object accelerate upward by 3m/s??
C. What is the acceleration and tension in the rope when F is zero?
