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.

Objects 1 and 2 are shown below. Object 1 has mass 21 kg, object 2 has mass 7.kg, and the kinetic
coefficient of friction for object 1 on the table is 0.31. If object 1 is pushed so that it is moving away from
the pulley, then find the magnitude of the acceleration of each mass and the tension in the string.
