Homework Help: Kinetic friction, pulley, inclined plane

  1. Sep 9, 2008 #1
    1. The problem statement, all variables and given/known data


    blocks 1 and 2 of masses m1 and m2 respectively, are connected by a light string. these blocks are further connected to a block of mass M by another light string that passes over a pulley of negligible mass and friction. blocks 1 and 2 move with constant velocity v down the inclined plane, which makes an angle (theta) with the horizontal. the kinetic frictional force on block 1 is f and that on block 2 is 2f.

    Determine the coefficient of kinetic friction between the inclined plane and block 1.
    2. Relevant equations

    F=ma
    F=uN

    3. The attempt at a solution

    N=mgsin(theta)+mg

    i don't know where to go from there
