Final speed of two billiard balls

  1. Oct 25, 2007 #1
    Both have mass of .5 kg and speed of 2.8 m/s; collide completely inelastically

    Do I use the conservation of momentum formula? v2= m1/m1 + m2 * v1?

    Ugh.

    Use conservation of momentum. (Not sure about that formula, though.) Why not post the exact problem?

    A billiard ball with mass .5 kg has a speed of 2.8 m/s and collides completely inelastically with a ball of same mass.

    Find the final speed of two balls.


    What formula do you know for the conservation of momentum?
    Thanks!

    The formula you quoted will work fine for this problem.
