. If the spring-block system are in equilibrium as shown below, the ramp is frictionless, the mass of the spring is negligible.  = 30. and m = 2.0x102 g. What is the scale readings in this case? Draw free body diagrams of the spring and the block and show your calculation.

i need help creating a graph using excel or simular for my data in the attached photo. Thanks

Two students want to determine the coefficient of kinetic friction of leather on oak for an experiment in their physics class. They have a block wrapped in leather that weighs 2.2 kg and notice that when they pull the block with a spring scale, the maximum force it reaches before Nie block starts to move is 13 N, and after the block starts to move the scale reads 11 N. What is the coefficient of kinetic friction? a. 5.9 b. 0.51 с. 5.0 d. 0.60

Figure B 0.500 m Part C Block A has a mass of mд = 42.0 kg and rests on a flat surface. (Figure 3)The coefficient of static friction between the block and the surface is μA = 0.210. The coefficient of static friction between the rope and the fixed peg B is 0.340. The width of the block is d=0.200 m. Find the greatest mass, mc, that weight C can have such that block A does not move. Express your answer numerically in kilograms to three significant figures. ▸ View Available Hint(s) ΜΕ ΑΣΦ ↓↑ vec mc 30.6 T 0.200 m A 0.300 m Submit Previous Answers 0.400 m- × Incorrect; Try Again; 19 attempts remaining ? kg
