A system involving Tension

  1. Feb 17, 2009 #1
    1. The problem statement, all variables and given/known data

    The figure shows two 1.0 kg blocks connected by a rope. A second rope hangs beneath the lower block. Both ropes have a mass of 250 g. The entire assembly is accelerated upward at 3m/sec^2 by force F.

    What are the following tensions:

    1. The tension of the top of rope 1.
    2. The tention of the bottem of rope 1.
    3. The tension of the top of rope 2.

    Includes the following diagram
    [A]
    |1

    |2


    2. Relevant equations
    Fnet = 2.5*-9.8+F
    T=g(mass of all things under it)

    3. The attempt at a solution

    Tsub1 = (.25+.25+1)g
    Tsub2 = .25g

    But these answers are wrong...

    Can't make sense of it with no diagram.
