  1. Sep 20, 2007 #1
    1. The problem statement, all variables and given/known data

    Two blocks m1 = 8.5 kg and m2 = 4.0 kg are connected by a homogeneous rope that has a mass of mr = 1.14 kg. A constant vertical force, F = 180.4 N, is applied to the upper block. What is the magnitude of the acceleration of the system?

    2. Relevant equations


    3. The attempt at a solution

    I've got no clue! Can neone help?

    Is gravity involved, or is this the only force acting on the system?

    What is the total mass of the system?
