Homework Help: 3 body collision

  1. Oct 29, 2006 #1
    What equation should I use to represent a 3 body inelastic equation .. two ball of different masses falling together and colliding with the stationary ground.

    And any hints on deriving the two body equation shown below

    momentum before equals momentum after.

    or you could calculate the centre of mass. but that would only work for a two body collision (i think).

    Why don't you describe the exact problem you are trying to solve?

    Im writing a research essay on balls of different mass falling from a fixed height onto the floor. Divided into two parts, I first vary the mass of the top ball and then for the next part I vary the mass of the bigger base ball. No Im using the general inelastic equation.. attached above and I need to go about first deriving it and then incoporating a collision with the floor. So a 3 body collision?
