The "FLOP"

Conservation of Momentum for a Two Particle System: p1 = p2, where p1 = m1v1 and p2 = m2v2, therefore m1v1 = m2v2 and v2 = (m1v1)/m2.

Let m1 be greater than m2. t is time, and (t)i is t before the contact between m1 and m2. (t)f is t after the contact between m1 and m2.

From v2 = (m1v1)/m2, v2 at (t)f will be greater than v2 at (t)i. If m1 is significantly larger that m2, and at (t)i v1 is significantly larger that v2,, then v2 at (t)f can be significantly larger V2 at (t)i. Therefore, it is possible for a slight bump by Player #1 against Player #2 can send Player #2 into the third row.
