    Hi all,
    I'm really stumped at this question five of my assignment. Could anyone please give me some help? I don't even know where to start.

    Start by drawing yourself free body diagrams for each mass. Apply Newton's 2nd law to each.

    (The peg can be thought of as a pulley, if that helps.)
