A 1,401.448 N painter needs to climb d=2.295 m up a ladder (measured along its length from the point where the ladder contacts the ground), without the ladder slipping. The uniform density ladder is 9.337 m long and weighs 250 N. It rests with one end on the ground and the other end against a smooth andfrictionless vertical wall. The ladder rises at an angle of theta=62.327º above the horizontal floor. What is the friction force in units of N that the floor must exert on the ladder? Use g = 9.8 m/s2.
