A uniform ladder weighing 180N is leaned against a smooth vertical wall at 53.1o
. A person
weighing 800N stands on the ladder a distance 1m from the bottom, as measured along xaxis. The foot of the ladder is 3m from the bottom of the wall. The center of mass of the
ladder is in the middle of it. What is the force exerted by the wall on the ladder? What is the
normal force exerted by the floor on the ladder? What is force of friction between the
ladder and floor?
