Homework Help: Typical Forces and friction question

  1. Mar 18, 2008 #1
    [solved] Forces and friction

    Hi guys :]

    1. The problem statement, all variables and given/known data
    A box (A) slides up a ramp due to the mass of the attached box (B).
    Given the acceleration and ramp length, determine the force of tension and force of kinetic friction.


    2. Relevant equations
    Fnet=ma
    Fg=mg

    3. The attempt at a solution
    I only got as far as finding the Fnet by multiplying the combined masses and given acceleration. Where do I go from here?
    I don't need numerical values, just.. can someone enlighten me on how I should approach this question, so I can find the kinetic friction and tension forces?

    Any help is greatly appreciated, thanks :redface:!

    I think kinetic friction is found by multiplying the friction coefficient by normal force. So the normal force must be found. Not really sure about tension.
