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&Vpalloon will push the balloon upward. If the balloon has a diameter of 12 m and carries two people, 85 kg each, determine the acceleration of the balloon when it is first released. Assume the density of air is p = 1.16 kg/m², and Answer: 22.4 m/s? 1-101 neglect the weight of the ropes and the cage.
