In the figure, a ladder of weight 200 N and length 10 meters leans against a smooth wall (no friction onwall). A firefighter of weight 600 N climbs a distance x up the ladder. The coefficient of friction betweenthe ladder and the floor is 0.5. What is the maximum value of x if the ladder is not to slip?
