Question

Using the dimensions given in the figure, find the magnitudes of f1, f2 and f3 . Express your answer using two significant figures.
f1 = (?) kN
f2 = (?) kN
f3 = (?) kN

An 72 kg person stands on a uniform 6.4 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.
