Double Ball Drop

  1. May 30, 2009 #1
    I'm having a problem with this problem:

    Two balls of different mass are dropped one in top of the other, more precisely the one with the smaller mass on top.

    How can i figure out the velocity of both balls after the collision with the ground?

    I know this is a very trivial linear momentum problem, but i just can't get my head around it.

    Can someone enlighten me?

    (sorry for posting this tipe of question here, i'm new to the forum and i just realized that i should post this in the homework tab, btw, how can i delete posts or move them to another place?)

    Assume reflection with the ground has just reversed the velocity of the bottom ball.
