1. A person (40 kg) is managing to be at rest between two vertical walls by pressing one wall A by his hands and feet and the other wall B by his back (figure 6-E11).
Assume that the friction coefficient between his body
and the walls is 0.8 and that limiting friction acts at all
the contacts. (a) Show that the person pushes the two
walls with equal force. (b) Find the normal force exerted
by either wall on the person. Take g = 10 m/s?
