Three balls with masses of 5 g, 1 g, and 7 g,(adsbygoogle = window.adsbygoogle || []).push({});

respectively, are connected by massless rods.

The balls are located (in meter intervals) as

in the figure.

Imagine the first quadrant of a graph.

The 5 gram is at point (3,8)

The 7 gram is at point (5,2)

The 1 gram is at point (9,6)

What do do to find the center of gravity? I've looked online and I only see formulas for 2 objects instead of 3 so I'm stuck. Forgot to say they are all connected by massless rods.
