Homework Help: Force exerted on one object by another

  1. Feb 23, 2010 #1
    1. The problem statement, all variables and given/known data
    http://lon-capa.bsu.edu/res/brookscole/serway/College_Physics_7ed/serwaypictures/sf4_27.jpg

    m1=1.2kg
    m2=2.3kg
    m3=3.1kg
    a[of the system] determined to be = 6.36m/s^2
    T[between the cord of 1-->3] determined to be =22.27N

    Determine the force exerted by the number 1 block on the number 2 block.
    2. Relevant equations
    Newton's Second Law, I imagine; sigma F = mass*acceleration

    3. The attempt at a solution
    if the two were connected via a cable or something, I'd get how to do it; as stands, I'm not really sure. we've only went over this briefly, so I'm quite stumped.
    any help would be appreciated, however!

    A clearer explanation of the setup of all blocks, ropes, and pulleys would be helpful.

    I put up an image showing it, but it isn't displaying, now.
    I'll put it up again.
