A uniform ladder of 7.0 m long weighing 450 N rests with one end on the ground and the other end against the perfectly smooth vertical wall. The ladder increases at 60.0 degrees above the horizontal floor. The 750 N painter finds that she can climb 2.75 m up the ladder measured all along its length, before it starts to slip. Find out the friction force and normal force which the floor applies on the ladder?
