The Tale of Two Boxes. Consider the system consisting of two boxes and a rough inclined plane as shown. Box A has a mass of 4.00 kg, and box B has a mass of 5.50 kg. Once box B is set into downward motion, it descends at a constant speed. Assume that the pulley is light and frictionless, and the rope connecting the blocks is light and taut during the motion. Draw the free-body diagram of each box. Write down the equations of motion for each box. What is the magnitude of tension force on the rope?? What is the magnitude of kinetic friction exerted by the inclined surface on box A? ( What is the coefficient of kinetic friction between box A and the inclined surface? ( 37.0⁰
