A ladder 5m long rests on a horizontal ground against a smooth vertical wall at an angle of 70o with the horizontal. The weight of the ladder is 300N. The ladder is on the verge of sliding when a man weighing 750N stands on the ladder 1.5m from the bottom of the ladder. Calculate the coefficient of friction between the ladder and the floor.
