Question

A 5 m long ladder weighing 300 N rests on a floor and against a wall. The ladder makes a 60 angle with the ground. For all contact surfaces the coefficient of friction is 0.2. The center of gravity of the ladder is at a distance of 2m from point B. A man weighing 600 N moves up the ladder. Find the distance he covers when the ladder slips.
