Posted by Jen on Friday, August 2, 2013 at 1:32pm.

2 objects are connected on an inclined table. The objects have masses 8.0kg, 4.0kg, and 2.0kg, and the pulleys are frictionless. (The one that is 8.0 is suspended from a pulley off the left side of the table, 4.0kg is on the table, and 2.0kg is suspended from the pulley of the right side.) The tabletop is rough, with a coefficient of kinetic friction of 0.47, and makes an angle of 20 degrees with the horizontal.
-Draw a free-body diagram for each object.
-Determine the acceleration and direction of motion of the system.
-Determine the tensions of the 2 cords.
