Two equal masses of 2.0 kg are at the ends of a 1.00 kg mass and 120.0 cm-long rod. The rod spins at 30.0 rpm about an axis through its midpoint. Suddenly, a compressed gas expands the rod out to a length of 180 cm. What is the rpm of the system after the expansion? Find speed of masses before and after expansion.
