(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?
