Problem
Two identical solid spheres (each of mass m) are connected by a light rigid rod of length L. The assembly translates horizontally at constant speed while simultaneously spinning about the midpoint of the rod. If you model the entire assembly as a single particle of mass 2m located at the midpoint when computing its total kinetic energy, will your calculated value be too large, too small, or correct? Briefly justify.
