A small box is held in place against a rough vertical wall by someone pushing on it with a force directed upward at 32° above the horizontal. The coefficients of static and kinetic friction between the box and wall are 0.45 and 0.35, respectively. The box slides up with acceleration a= 0.8 m/s2 when the applied force has magnitude 93 N.
a) Draw the free body diagram for the box?
b) Calculate x and y components of the applied force?
c) What is the mass of the box?
