1. The problem statement, all variables and given/known data Assuming that the combined mass of the balls is greater than the combined mass of the cords, but that the cords do have some mass, where is the center of mass for the system shown below? 2. Relevant equations None 3. The attempt at a solution I tried approaching this problem by finding the center of mass for the two balls first. I picked a point closer to the lower ball which is heavier. However I don't know how I would find the center of mass of the cord?? Is the center of mass usually closer to heavier objects. I think I need a conceptual understanding of the center of mass.
