A small box is held in place against a rough vertical wall by someone pushing on it with a force directed upward at 25 above the horizontal. The coefficients of static and kinetic friction between the box and wall are 0.40 and 0.30, respectively. The box slides down unless the applied force has magnitude 13 N. Part A What is the mass of the box? Express your answer using two significant figures.
