A 9.8 m ladder whose weight is 257 N is

placed against a smooth vertical wall. A

person whose weight is 464 N stands on the

ladder a distance 1.9 m up the ladder. The

foot of the ladder rests on the floor 7.056 m

from the wall.

Calculate the force exerted by the wall.

Answer in units of N.

Calculate the normal force exerted by the

floor on the ladder.

Answer in units of N.

2. Relevant equations

Tnet = 0

Fnet = 0

3. The attempt at a solution

I know I need to pick a point of rotation. I figured I would pick the bottom of the ladder where it makes contact with the floor. That will eliminated the torque due to the friction force and the normal force between the ladder and the floor. The other forces are the weight of the ladder, weight of the man, and the friction force of the ladder and wall. I'm kind of lost now.
