Two objects, both mass m, are going opposite, parallel
directions at a speed v. They simultaneously hit and stick to a rod
of length L and mass M. The rod is positioned perpendicular to the
paths of the two objects.

the collision? What are the initial and final values?
b) Is any mechanical energy lost in the collision? If not, why
not? If so, how much?
