Homework Help: Finding g and Atwood's machine

  1. Sep 13, 2008 #1
    Hi!
    I have an assignment to write a mini-essay of sorts on Atwood's machine. One of the things I need to cover is how to find the value of g by using Atwood's machine. I really have no idea how to do this. I was thinking about rearranging a= [(m2-m1)g] / (m1+m2) but I don't understand how to get a.
    Help would be greatly appreciated!

    If you are using this to find g, you'd have to measure the acceleration.
