A man is pulling two boxes, one on top of the other, up the ramp shown by pulling on a rope parallel to the surface of the ramp. The coefficient of kinetic friction between the ramp and the lower box is 0.444, and the coefficient of static friction between the two boxes is 0.800. What is the magnitude of the maximum acceleration the man can pull the boxes up the ramp without having the top box slip off the bottom box?
