    angle = 20
    coefficient of kinetic friction between block and surface = 0.2
    When the whold system released, what is the "acceleration" of blocks.
    all blocks have equal mass

    2. Relevant equations

    3. The attempt at a solution
    block c will lead the motion

    What are your thoughts on the matter? In the past, how have you treated problems involving blocks, strings and hanging masses? Other than reading the problem carefully, where does one always begin with such problems?

    Hi wing_88! :smile:

    Either call the two tensions T1 and T2, then do some FBD equations, and eliminate T1 and T2

    or use work done and conservation of energy. :wink:
