Finding Force of Friction Help

  1. Nov 24, 2011 #1
    1. The problem statement, all variables and given/known data
    ok, so in need to find the force of friction applied onto a model rocket. I dont want the answer, but how to find thr force of friction


    2. Relevant equations
    i know that FfkFn
    Fn=mg

    but i dont know how to find μk

    What's the situation? Unless your model rocket is sliding across a surface, kinetic friction will not be relevant.

    You want to explore air resistance and drag, not kinetic friction.
