In this problem, we're asked to determine the tension in a system involving multiple objects.
You might remember this kind of arrangement is called an Atwood Machine.
As usual for any problem that involves a system of objects, we'll follow these steps:
In step 1, we'll need a positive direction of motion to guide the sign conventions for the motion of the two masses.
Suppose the pulley in the figure is suspended by a cord C.
Determine the tension in this cord after the masses are released and before one hits the ground. Ignore the mass of the pulley and cords.
