Problem involving pulleys

  1. Mar 19, 2008 #1
    1. The problem statement, all variables and given/known data
    Determine the tension developed in the cords attached to each block and the accelerations of the blocks. Neglect the mass of the pulleys and cords. I have attached the picture below.


    2. Relevant equations
    Fnet=ma


    3. The attempt at a solution

    W=mg=(6*9.8)
    I have no idea how to proceede any further

    … give the lengths names …

    Hi myoplex11! :smile:

    The first thing to do is to give the lengths of the cords letters, such as a and b.

    I haven't seen the picture yet, so I don't even know if there's two blocks, but I assume a + b is a constant, so you can call that c, and then eliminate b by putting b = c - a.

    Then you use your F = mx´´ equation to get an equation in a´´. :smile:
