Homework Help: Another pulley system

  1. Jul 6, 2010 #1
    1. The problem statement, all variables and given/known data
    Body B in the figure weighs 102N and Body A weighs 32N, The coefficients of friction between B and the incline are Ms=0.56 and Mk=0.25. Find the acceleration of the system if
    a) B is initially at rest
    b) B is moving up the incline
    c) B is moving down the incline


    2. Relevant equations
    i don't understand which equations i would need

    3. The attempt at a solution
    what's the difference in situation between a, b, c i dont understand how i could solve them differently
    i am so confused!

    I gave a post about this on the other problem.
    Your link does not work so if someone else wants to help tonight you might want to change it.
