calculation

An oxygen molecule at rest is hit by an Ar atom. They form a weakly bound complex. What speed does the complex move off with?
Calculate the initial kinetic energy of the Ar atom and the final kinetic energy of the complex. The calculated kinetic energy of the complex must be smaller then the energy of the incident Ar atom. Where is the rest of the energy?

I don't understand how to calculate any of this without being given the velocity of Ar atom... or a temperature to calculate it...

it's proportions based on momentum
