A person climbs up a ladder to the position shown in the figure. The ladder weighs 32.05 lb., while the person weighs 187.08 lb. The center of mass of the 10-ft ladder is at its midpoint. The angle α = 37°. Assume that the wall exerts a negligible friction force on the ladder. If x = 4.81 ft., what is the magnitude of the friction force (in lb.) exerted on the ladder by the floor?
