A m1 = 1.35-kg aluminum block and a m2 = 6.85-kg copper block are connected by a light string over a frictionless pulley. The two blocks are allowed to move on a fixed steel block wedge (of angle ? = 31.5°) as shown in the figure. (For aluminum on steel, ?s = 0.61and ?k = 0.47. For copper on steel, ?s = 0.53 and ?k = 0.36.) Answer parts a-b.
