Homework Help: D-2 motion.

  1. Feb 12, 2008 #1
    I'm at the last equation of my homework and I'm stuck

    1. The problem statement, all variables and given/known data

    In a nuclear reactor, a neutron moving at speed vo (vo is initial speed) in the positive x direction strikes a deuteron, which is at rest. The neutron is deflected by 90 degrees and moves off with a speed vo/*square root of three* in the positve y direction.

    2. Relevant equations

    Find the x and y components of the deuteron's velocity after the collision. The mass of the deuteron is twice the mass of the neutron.

    3. The attempt at a solution

    I tried, but I don't get it.
    Plz help me show work if you can thxs.
