Forces and Motion problem

  1. Nov 15, 2009 #1
    1. The problem statement, all variables and given/known data
    If the balloon in the diagram drawn below is accelerating upwards at 0.40 m/s (squared), calculate the tension in each piece of rope. Assume that the rope has no mass.

    The diagram: 2d0kyyt.jpg

    2. Relevant equations
    F = ma

    3. The attempt at a solution
    For the bottom piece of rope
    Fnet = Fa - Fg
    Fnet = ma - mg
    Fnet = (9.00)(0.40) - (9.00)(9.8)

    where Fnet is the tension in the piece of rope, Fa is the force accelerating the balloon upwards, and m is the mass of the object held up by the rope
