Relativistic dynamics-collision problem

  1. Mar 18, 2012 #1
    I WOULD BE VERY THANKFUL IF ANYONE COULD PLEASE ME WITH THIS PROBLEM! :)

    Particle 1 with mass m1 encouters elastic collision with particle 2 which has mass m2
    Assume that particle 2 is stationary before collision.
    And movement-direction of particle 1 after collision, is perpendicular to the movement-direction before collision.
    Let T1 symbolize kinetic-energy of particle 1 before collision
    And p'1 momentum of particle 1 after collision

    a) show that the angle between the movement-direction of particle 2 after collision and movement-direction of particle 1 before collision if θ where
    tanθ = lp'1l / sqrt(2T1m1+T1^2/c^2)
    b)show that after collision, length of the momentum-vector of the particle 2 is
    sqrt( lp'1l+2T1m1+T1^2/c^2)

    what does c refers to in the ans.

    c= The speed of light in vacuum
