Blocks of mass mA=6 kg and mB=4 kg subjected to a force of 25 N.
Two blocks, of masses mA = 0.35 kg and mB = 1.15 kg, are on a frictionles horizontal surface, the blocks are connected by a rope with negligible mass. A horizontal force of constant magnitude equal to 15 N is applied by pulling the two blocks. Find the magnitude acceleration acquired by the system and the tension in the rope connecting the blocks.
