Momentum & Collision Problem

  1. Oct 22, 2012 #1
    1. The problem statement, all variables and given/known data
    Consider a head-on collision between two people. The damage done to each person is far greater if the people rebound upon impact versus sticking together upon impact. Why? Discuss in terms of impulse/change in momentum.


    2. Relevant equations
    Momentum = (mass x Volume of 1st person)(Massx Volume of second person)


    3. The attempt at a solution

    I'm pretty lost.

    You have been doing work on collisions in class.
    What conservation law do you normally use?

    That Momentum is always conserved

    If they rebound then they will encounter a second collision with the floor.

    Fine - so how would you normally use this law?
