Question

a woman who weights 5.00x10^2 N is leaning against a smooth vertical wall, as the drawing shows.find the force exerted on her shoulders by the wall and the horizontal (F2) and vertical components of the force (F1) exerted on her shoes by the ground.
the angle is 60 degrees. from her shoes to her stomach is 1.10m and from the neck to the stomach is 0.400m.

Answer 1

Assuming no friction on the wall, only normal forces.

Summing moments about the shoe:
500*1.1-(Fwall)*(.4+1.1)*cos60=0
solve for Fwall
summing vertical forces:
F1-500=0 solve for F1.
summing horizontal forces:
F2-Fwall=0 solve for F2, the friction force on the shoe to keep it from sliding.
