An 85kg person stands on a uniform ladder 4.0m long, that weighs 100N, as shown in the figure. The floor is rough; hence, it exerts both a normal force, f1. and a frictional force, , on the ladder. The wall, on the other hand, is frictionless; it exerts only a normal force, fs. The ladder makes angle of 60.0 with the floor. Find the forces exerted on the ladder when the person is three-fourths of the way up the ladder.

A uniform ladder stands on a rough floor and rests against a frictionless wall as shown in the figure. Since the floor is rough, it exerts both a normal force n, and a frictional force r, on the ladder. However, since the wall is frictionless, it exerts only a normal force N, on the ladder. The ladder has a length of L = 4.3 m, a weight of w. = 67.5 N, and rests against the wall a distance d...
