Am, = 1.85-kg aluminum block and a m, = 7.45-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 8 = 32.00) as shown in the figure. (For aluminum on steel, u. = 0.61 and u, = 0.47. For copper on steel, u = 0.53 and u, = 0.36.) Aluminum Copper Steel (a) the acceleration of the two blocks m/s2 (b) the tension in the string
