A (3.1110 kg) mass rests on a frictionless table. It is attached by a light—weight thread passing over a light, frictionless pulley to a 1m kg mass hanging in the air. The upper mass is held stationary and then released. a} For each mass, dramI a free—body diagram showing all forces. In] Find the magnitude of the acceleration of the two-mass system. c} Find the tension in the thread connecting the two masses. d] A student tries to set up this experiment in the laboratory, but cannot ?nd a sun k5 mass. She improvises by tying a 1.00 kg mass and a Lil} kg mass together as shown. Compute the L Frictionlcss tension in the cord connecting the 1.13:] kg and .
