Homework Help: Theoretical Fusor Momentum Quandary

  1. May 10, 2009 #1
    I am have the initial velocities and masses of nuclei involved in fusion, and am trying to figure out the resulting velocities and kinetic energies. Since this is an inelastic reaction, i cant use Kinetic energy, as it is not conserved. I have the conservation of momentum to use, because it is conserved, but to use it I still need to find velocity. What could i use to find this? Also, if you could clarify how to find the kinetic energies for each resulting particle, it would be greatly appreciated!

    Deuterium+Deuterium--> Helium-3 + neutron
    each deuteron has K.E. of 69.91 KeV, and a velocity of 2.59 x 10^6 m/s
