Problem 41E

A balloon floats motionless in the air. A balloonist begins climbing the supporting cable. In which direction does the balloon move as the balloonist climbs? Defend your answer.

Step-by-Step Solution:
Step 1 of 3

The balloon will move down as the balloonist transfers his weight onto thecable. If the balloon has enough buoyancy in air, enough lift, it will return back up to the position it was when our climber approached the support cable. This assumes the balloon is tethered to the ground and has just a bit more lift than the opposing mass of the balloon and the climber. The balloon will have lifted the balloonist up along with its own bulk. As he moves up the cable, unless he moves very slowly. Again, this is for a balloon capable of lifting itself and the balloonist, but which only has a bit more buoyancy...
