Homework Help: Quantum dynamics

  1. Dec 3, 2008 #1
    1. The problem statement, all variables and given/known data

    there are 2 particals with the same mass and they undergo two different experments in expermant 1 partical 1 is moveing at .9c and partical two is at rest it wanted the KE before they hit and i got 1.29mc^2 (i checked it in my book) for experment two the total KE before the particals hit is 1.29mc^2 and both particals are moveing at eagh other at a velocity U it wanted me to find u so i set 1.29mc^2= 2c^2m(Y) and got u to be .795c ( i also checked that in my book) part c said that the particals in part a and b stick together and it wanted me to find the resalting masses that would resalt after the particals hit in both experments.

    2. Relevant equations

    i don't know where to start or what equation to use so could someone help me get started.


    3. The attempt at a solution
