Question help (not homework)

  1. May 24, 2010 #1
    If a ball has a mass of m1 and a velocity of v1, and collides with a second ball with a mass of 20 times m1 (m2=20xm1) and m1 rebound with a velocity of –v1 and is the velocity of m2?
    and m2 velocity is 0 before impact

    Just use conservation of momentum. Be careful of one thing - are you assuming that the directions after collision are along the same line as that before? Otherwise the problem statement is incomplete. If along line, then v2=v1/10.
