Velocity Lost To Friction

  1. Mar 2, 2010 #1
    1. The problem statement, all variables and given/known data
    If you had a track that was in the shape of a loop-de-loop and you send a small brass ball down the track, how would you calculate how much velocity is lost due to friction?
    The radius of the loop is .15m.

    2. Relevant equations
    V = (2πr)/[tex]\sqrt{}(4(\pi^2)r)/g[/tex]

    3. The attempt at a solution
    I don't know what equation to use to find the loss of velocity due to friction so I'm not sure how to go about solving the problem.
