Homework Help: Mass & Acceleration Proportion

  1. Sep 28, 2009 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    [MATH]F=ma[/MATH]


    3. The attempt at a solution
    I'm having trouble because the original acceleration is positive and the final one is positive. How do I set up the proportion with what I have? Setting [MATH]-305*1.4=m_2*1.3[/MATH] doesn't work.

    What is the acceleration of the freely falling balloon?
    why the balloon's acceleration is reduced?
    What is the net acceleration of the balloon when it is moving up?
