Hello everyone, I have a problem here from "Physics for scientists and engineers"...

A system of two stars of mass 1.99*10^30 kg each, have distanse of 1.0 *10^12 meters from eachother. A comet that is very very far away is slowly pulled from the stars by the force of gravity. Assuming that the comet is traveling through a straight line crossing excactly between the two stars, what is the velocity of the comet when it passes between them?

I didn't check the numbers but the method is good.
