A rope is attached to an object with mass 8.5-kg that rests on a frictionless, horizontal surface. The horizontal rope passes over a pulley, and a block with mass 5 kg is suspended from the other end. When the blocks are released, the tension in the rope is 11.6 newtons. What is the acceleration of either block? The pulley is frictionless and massless.
