A helium balloon ride lifts up passengers in a basket. Assume the density of air is 1.28 kg/m3 and the density of helium in the balloon is 0.18 kg/m3. The radius of the balloon (when filled) is R = 5.3 m. The total mass of the empty balloon and basket is mb = 120 kg and the total volume is Vb = 0.059 m3. Assume the average person that gets into the balloon has a mass mp = 72 kg and volume Vp = 0.078 m3.1) What is the volume of helium in the balloon when fully inflated?m3Your submissions:2) What is the magnitude of the force of gravity on the entire system (but with no people)?
