F h = (“slope”) x + (“y-intercept”), where the “slope” is mg/h and the “y-intercept” is MgD /2 h . Since h = 0.480 m and D = 4.00 m, and the graph seems to intercept the vertical axis at 20 kN, then we find M = 500 kg. (b) Since the “slope” (estimated from the graph) is (5000 N)/(4 m), then the man’s mass must be m = 62.5 kg.
