4. Three bodies A, B, and C are connected by two cords as shown so that all three bodies move with the same acceleration. The pulley is assumed to be weightless and frictionless. Body A weighs 36 Ibs, B weighs 60 lbs, and C weighs 120 lbs. The coefficient of kinetic friction for A and the plane is 0.25, and for B and the plane 0.2. Find: a. The acceleration of the bodies. b. The tension T, in the cord between A and B. c. The tension T2 in the cord between B and C. a В а A C 0 = 30°
