(II) A small box is held in place against a rough verticalwall by someone pushing on it with a force directed upwardat 28° above the horizontal. The coefficients of static andkinetic friction between the box and wall are 0.40 and0.30, respectively. The box slides down unless the appliedforce has magnitude 23 N. What is the mass of the box?
(I) A box weighing 77.0 N rests on
a table. A rope tied to the box runs
vertically upward over a pulley and
a weight is hung from the other
end (Fig. 4–45). Determine the
force that the table exerts on
the box if the weight hanging
on the other side of the pulley
weighs (a) 30.0 N, (b) 60.0 N, and
