Given: The wall is frictionless. The mass of the ladder is m.

sebastian has drawn a free-body diagram for a ladder of mass m leaning against a frictionless wall. His diagram is shown below. What is his error? N. A 7N is in the wrong direction. Iy should be directed upwards, not down. should be perpendicular to the wall, not parallel to it. D Iy should be down into the floor for , to have the given direction. E 7y is correct, but there should also be a force perpendicular to the wall.
