Vierd doubt about object collisions

  1. Jan 31, 2012 #1
    I just got a doubt regarding object collisions and could not find any relevant information on web. I suppose to put on my question here for help.

    when the two objects that are independent or dependent together are colliding each other, an other third object want to pass through these objects without any collisions with the reaming objects that are already attracting together. So, if i know the speed of the two objects that are in colliding together. How can i find the required speed of the third object to throw through those objects?

    Any help would be appreciated.

    Sounds like this is a kinematics question, not really much to do with collisions. Figure out how much time before the objects collide. Then use that to determine how quickly the third object must move to pass between them before they collide.
