Homework Help: Particle projection, momentum. Somewhat .

  1. May 19, 2010 #1
    Particle projection, momentum. Somewhat urgent.

    1. The problem statement, all variables and given/known data
    I didn't properly explain myself last time. I've included a diagram for reference.

    Two particle of masses m and 3m are connected by a light rigid rod. The system rests on a smooth horizontal table, the heavier mass due east of the lighter mass. The heavier mass is projected with initial velocity [tex]u j^>[/tex]. Find the velocities of the particles when the rod runs north-south.

    2. Relevant equations

    Energy, momentum.

    3. The attempt at a solution
    I applied momentum to the upward direction, and then applied conservation of energy. I end up with too many variable and am quite unsure how to solve this problem. any hints would be greatly appreciated. :smile:
