IYGYR The kinetic coefficient of friction for a 12 kg mass on a table is 0.25. A string from this mass goes across a pulley and is attached to an 8.0 kg mass hanging over the side of the table. If the system is moving so that the hanging mass is moving downward, then find the magnitude of the acceleration of each mass and the tension in the string. 19. acceleration A. D. B.
