3 kg4 kg 28 cm 28 cmTwo uniform rods of equal length and unequal masses are connected by a massless and frictionless hinge. Initially, the rods are at rest, forming an equilateral triangle with a frictionless surface. At time t = 0 the lower ends of the rods begin to slide apart with only the force of gravity acting upon the system.

When the system comes to rest, how far has the hinge moved horizontally from its original position?
