- The systems shown in Figure P4.22 are in equilibrium. If the spring scales are calibrated in newtons, what do they read? Ignore the masses of the pulleys and strings and assume the pulleys and the incline in Figure P4.22d are frictionless. Figure P4.22In Figure 1, we depict two boxes and an applied force of magnitude 100.0N. The horizontal floor is frictionless, and box A is more massive thanbox B. Which of the following is correct? (Before you answer this question, draw FBDs and sum forces.)a. Box A pushes on box B with a force of 100 N, and box B pusheson box A with a force of 100 N.b. Box A pushes on box B harder than box B pushes on box A.c. Boxes A and B push on each other with equal forces of less than 100.0N.d. The boxes will not begin to move unless the total weight of the twoboxes is less than 100.0 N.A set of eight boxes, 5.0 kg each, are stacked on top of a table, as shown in the figure below.

Suppose the system of blocks is initially held motionless and, when released, begins to accelerate. If m1 = 7.25 kg, m2 = 2.25 kg, and the magnitude of the acceleration of the blocks is 0.150 m/s2, find the magnitude of the kinetic frictional force between the second block and the ledge.
