+ 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 forcef, on the ladder. However, since the wall is frictionless, it exerts only a normal force N₂ on the ladder. The ladder has a length of L = 4.2 m, a weight of W, = 66.5 N, and rests against the wall a distance d = 3.75 m above the floor.
