Homework Help: Urgent. I just need the Kinetic Coefficients

  1. Jan 14, 2010 #1
    1. The problem statement, all variables and given/known data
    I have searched very long time. I need the kinetic coefficient of Polystyrene of Polystyrene, or even better Polystyrene on Glass. The polystyrene we are using is the stuff that is used to insulate hot water pipe.

    2. Relevant equations
    We do not know the weight of the polystyrene, and marble is glass and weighs 0.0053 kg

    3. The attempt at a solution
