Momentum and Collision

  1. Sep 24, 2009 #1
    Okay this is a question about after two balls collide knowing their speeds and directions and mass before collision, what is their speed and direction after collision in two dimensional space.


    more specifically i need to know this because i am programming a game in which i need accurate ball behavior so, assuming collision occurs at the origin, and ball one comes from x degrees and ball 2 comes from x degrees, and i know their speeds, and can make up a mass for them based on their size,

    how do i figure out their direction and speed? also note that at this point i am ignoring friction or anyother outside forces, but that will change in later development

    thanks for any help and guidance you could give me

    Cruncher,

    You need to use the equation for collisions. I don't know whether in your case it is elastic or inelastic. Write an equation for each dimension, one for all momentum in the x direction and one for all the momentum in the y direction.

    it is not elastic, it is as though 2 billiard balls hit eachother.. do you know where i could find these equations? thanks
