Two point masses, each of mass , are joined by a massless rigid rod of length and lie at rest on a frictionless horizontal surface. A third point mass slides along the surface with speed in a direction perpendicular to the rod, strikes one end of the dumbbell, and sticks to it on contact.
Immediately after the collision, what is the speed of the other (unhit) end mass?
