A 13 m ladder whose weight is 185 N is placed against a smooth vertical wall. A person whose weight is 953 N stands on the ladder. The foot of the ladder rests on the floor 2.99 m from the wall. Calculate the force exerted by the wall. Answer in units of N.

The force on the wall depends on how far up the ladder the person is standing. I am assuming that the coefficient of friction between the floor and the ladder is sufficiently high that it won't slip?
