A 1.29-m long ladder weighing 200N rests against a vertical wall so that the top of the ladder is at a height of .590m. A 603-N man stands on the ladder at a distance of .390m along the ladder. Calculate the force exerted by the wall on the ladder. Assume that the wall is perfectly smooth. Well.. i've never had to deal with a problem like this, so do not really know where to go from here. Do I need the equation Fnet=Fa+F+(-Fg) and solve for Fa? It seems like i need to find the torques? I really don't know what to do here.
