Part A This problem concerns the concept of tension in a rope. Consider a rope subjected to a pulling force on its two ends as shown in (Figure 1). The rope is stationary. An arbitrary point P divides the rope into a left-hand segment L and a right-hand segment R. For segment R and segment L to hold together, they must exert forces on each other. What is the direction of the force exerted on segment R by segment L? ▸ View Available Hint(s) Figure pull L pull R 1 of 3 > left right Submit Part B Assume that segment R exerts a force of magnitude T on segment L. What is the magnitude FLR of the force exerted on segment R by segment L? Give your answer in terms of T and other constants such as g. ▸ View Available Hint(s) FLR = Submit Part C ΕΠΙ ΑΣΦ ? Now imagine two points, Q and P, that divide the rope into segments L, M, and R. (Figure 2) The rope remains stationary. Assume that segment L exerts a force of magnitude FLM on segment M. What is the magnitude FRM of the force exerted by segment R on segment M? Give your answer in terms of FLM and constants such as g. Figure pull M pull R 2 of 3

You want to use a rope to pull a 12-kg box of books up a plane inclined 30° above the horizontal. The coefficient of kinetic friction is 0.28. The rope pulls parallel to the incline. Part A What force do you need to exert on the rope if you want to pull the box at constant speed. Express your answer with the appropriate units.

Need help with Part C

Pls help with the following and explain the right answer, thank you. part B. Find the direction of this force as the angle measured counterclockwise from the +x+�-axis directed horizontally to the right. Express your answer in degrees.

And also please part c what is the magnitude of the resultant force in newtons

Can you please answer this

Part D Assuming that the angle at which you push on the edge of the box is again 45°, with what magnitude of force Fp should you push if the box were to slide down the wall at a constant velocity? Note that, in general, the magnitude of the friction force will change if you change the magnitude of the pushing force. Thus, for this part, assume that the magnitude of the friction force is f = 0.516Fp. ► View Available Hint(s) Fp= [ΨΕΙ ΑΣΦ = ? N
