Homework Help: What is the comet's speed at the midpoint?

  1. Nov 23, 2006 #1
    A binary star system has two stars, each with the same mass as our sun, separated by 1.10×1012 . A comet is very far away and essentially at rest. Slowly but surely, gravity pulls the comet toward the stars. Suppose the comet travels along a straight line that passes through the midpoint between the two stars.

    My question is "What is the comet's speed at the midpoint?"

    Thank you!

    No hard feelings sir :biggrin: but one really cant teach anybody if he tries to learn while he teaches. He must be perfect in his own sense.
