A ladder 8 m long weighs 325 N with its center of gravity 2.43 m from the bottom of the ladder. The base of the ladder rests on a floor with a coefficient of friction of 0.8. The top leans against a smooth wall (no friction). What is the largest angle which the ladder can have with the floor and still permit a person weighing 950 N to climb to a rung 6.8 m from the bottom as measured along the ladder?
