Distribution of energy

  1. Nov 29, 2013 #1
    Hi,
    i´m reading Landau´s mechanics and in the 4th chapter in the part disintegration of particles (16) i can´t figure out the following thing. We have a function T=(1/2)m(V2)+(1/2)m(v02) + mVv0cos(θ) , where V and v0 are constant in this problem. We also know the distribution of θ which is (1/2)sinθdθ. The goal is to get a distribution of T. Could you please explain to me how to get it? The book derives it in a way i can´t understand. Thanks in advance.

    Welcome to PF;
    The trick is to understand what the distribution means - i.e. what would the "distribution of T" tell you, once you have it? What is the "distribution of ##\small \theta##" telling you?

    Thanks, i went through it once more with your advice in mind and i finally understand it.

    Well done :)

    The next step is to find someone who is struggling and see if you can get them to understand.
