Two blocks, one sitting on a table and the other heavier one hanging over its edge, are connected by a light string as shown in the figure. newton3.gif Block 1 has mass m1 = 3.43 kg and block 2 has mass m2 = 1.87 kg. What is the magnitude of the acceleration a of the blocks in m/s2? Use g = 9.8 m/s2.
