Linear momentum

  1. Feb 5, 2009 #1
    it is possible to predict the subsequence motion of two point mass after a linear collision, given ONLY their mass and velocity before the collision?
    thanks.

    Think about a billiards game. Would this be possible if your premise were true?

    if you mean snooker, yes, it's possible to predict, based on the assumption that no energy is lost and the balls are of the same mass. (assume correct, is it?)
    but u dont know the energy 'status' of the system after the collision, how do u predict?
