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:http://i36.tinypic.com/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
