An 88 kg person stands on a uniform 5.6 kg ladder that is 4.0 m long, as shown in the figure(Figure 1). The floor is rough; hence, it exerts both a normal force, f1, and a frictional force, f2, on the ladder. The wall, on the other hand, is frictionless; it exerts only a normal force, f3.

Using the dimensions given in the figure, find the magnitudes of f1, f2, and f3.
