A uniform ladder is 10 m long and weighs 200 N. The ladder leans against a vertical, frictionless wall at a height of h = 8.0 m. A horizontal force is applied to the ladder at a distance d = 2.0 m from its base (as measured along the ladder). Suppose the coefficient of static friction is .38; for what minimum value of the horizontal force applied will the base of the ladder just barely start to move TOWARD the wall? Be sure to draw in all forces acting on the ladder
