Dynamics: Collision with inclined plane

  1. May 6, 2015 #1
    1. The problem statement, all variables and given/known data
    I have two conceptual questions that I have written in read in my solution. The solution, and all the work, is correct. However there are two things that I am unsure as to why I am doing it. Thanks!

    2. Relevant equations

    Included in solution, although none should be needed as questions are conceptual.

    3. The attempt at a solution

    Can read the momentum question. With difficulty.
    Momentum isn't conserved because the plane exercises a force. Since it is smooth, it can only exercise a force perpendicular to its surface. Along the incline no force, so momentum conservation. Can't distinguish what your x, y, directions are. Make a better picture or type it out.
