A 50 gram ball moving to the right with a velocity of 0.6 m/s collides centrally with a 0.2 kilogram ball that is at rest. After the impact, the two balls rebound, with the heavier ball being observed to be moving to the right with a velocity of .24 m/s.

  1. original momentum = .050 * 0.6 + 0 = 0.03
    final =0.03 = 0.050* 0.24 + 0.20* v
    solve for v
