Typical Forces and friction question

    [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

    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.
