In a laboratory experiment on friction, a 139-N block resting on a rough horizontal table is pulled by a horizontal wire. The pull gradually increases until the block begins to move and continues to increase thereafter. The figure (Figure 1) shows a graph of the friction force on this block as a function of the pull. Part B Why does the graph slant upward in the first part but then level out? Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Reset Help fk = n From P = 0 to P = 75.0 N, the block is and the friction is fs = Hs P and has the value Figure < 1 of 1> moving since this prevents relative fs = P motion. This is why the graph has slope +1 for at rest this range of P. f(N) static From P = 75.0 N to P = 150.0 N, the block is 75.0 kinetic and the friction is 50.0 fk = kn and has the value 25.0 independent of P. This is why P (N) the graph is horizontal for this range of P. 25.0 50.0 75.0 100.0 125.0 150.0
