Homework Help: A question from assignment

  1. Sep 17, 2012 #1
    1. The problem statement, all variables and given/known data
    In the figure a box of mass m1 1.0kg, on a frictionless inclined surface is connected to another box of mass m2  2.0 kg . The pulley is massless and frictionless. An upward force of magnitude F = 6.0 N acts on m2 , which has a downward acceleration of 5.5 m/s2. What are (a) the tension in the cord and (b) angle  ?


    2. Relevant equations
    Fr=m*a


    3. The attempt at a solution

    I have attempted a solution and found an answer. Just need to know if it's right. It's quiz prep.
