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?”

Your relative from abroad sent your family a balikbayan box. Since you know that the laws of motion will help you move the box easily, you volunteered to bring it inside your house. You have two options: (a) pulling the box from a rope that makes an angle with the surface or (b) by pushing the box with a force that makes the same angle (but pointing downwards) with the surface. Which choice will you choose? Will the angle matter?
A 250 g container hangs at rest from two strings. The rope under tension Ty is directed at an angle g = 32° from the horizontal direction as shown. What are the tensions Ty and T2 (in N) in the two strings?
In a two-dimensional tug-of-war, Alex, Betty, and Charles pull horizontally on an automobile tire at the angles shown in the overhead view of the figure.

Note that the direction of Charles' force is not given. What is the magnitude of Betty's force?

10. Referring to the image to the right, the mass of Block 1 is m1=3.37kg while the mass of Block 2 is m2=8.38kg. The coefficient of kinetic friction between Block 1 and the inclined surface is μk=0.41. The inclined surface is at an angle θ=34.2∘above the horizontal. (a) Using the variables from the problem statement together with the acceleration due to gravity, gg, write an equation for the magnitude of the acceleration of the system. Hint: Based upon the numeric choices, Block 1 will accelerate up the incline while the suspended block, Block 2, accelerates vertically downward. (b) Calculate the magnitude, in meters per squared second, of the system's acceleration.
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!!!
