Two Attached Blocks shows a block of mass on a frictionless, horizontal surface. It is pulled by a light string that passes over a frictionless and massless pulley. The other end of the string is connected to a block of mass. Find the acceleration of the blocks and the tension in the string. Calculate the acceleration of the system, and the tension in the string, when the masses are M1: 5.00 kg and M2: 9.00 kg
