Fb Balloons are often filled with helium gas because it weighs only

Fb Balloons are often filled with helium gas because it weighs only about one-seventh of what air weighs under identical conditions. The buoyancy force, which can be expressed as F = Pair gVballoon, will push the balloon upward. If the balloon has a diameter of 12 m and carries two people, 80.0 kg each, determine the acceleration of the balloon when it is first released. Assume the density of air is p = 1.16 kg/m and the density of helium gas to be 1/7th of this. Neglect the weight of the ropes and the cage. Helium D= 12m Pho = Par M es The acceleration of the balloon when it is first released is m/s
