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

Part A
What is the minimum horizontal force F needed to make the box start moving in (Figure 1)? The coefficients of kinetic and static friction between the box and
the floor are 0.28 and 0.38, respectively.

For part B (answer is 0.28m) can you draw where the perpendicular distance between 48N forces is? And also can you show me the equation for part B? Because for part A (answer is 13.44N) I used M = Fx • Dy Fx is 84 kN and Dy is 16cm. I’m confused that the answer key for part B uses M = Fy • Dx M= 13.44 N•M Fy= 48 N I’m probably misunderstanding Dx at part B. So can you fully explain this question. Thank you!!!
