An 80 kg person stands 0.75 m from the bottom of a ladder (i. e. d = 0.75 m). the ladder leans against a frictionless wall at a 60° angle. if the ladder is 50 kg and is 2.5 m long what is the friction due to the floor, in newtons, on the ladder?
the ladder in the previous problem had a person standing on it. assume this person climbs up so that he stands 2.0 m from the bottom of a ladder (i. e. d = 2.0 m). what is the force exerted by the wall, in newtons, on the ladder?
