which can rotate about an axis perpendicular
to the system. The mass of each connecting
rod is negligible. Treat the masses as particles.
The x-axis is along the horizontal direction
with the origin at the left-most mass 5 kg.
The masses are separated by rods of length
5 m, so that the entire length is 2 (5 m).
Determine the x-coordinate of the center of
mass for the three-mass system with respect
to the origin.
Answer in units of m.
