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 = 4.9 m. The total mass of the empty balloon and basket is mb = 122.0 kg and the total volume is Vb = 0.074 m3. Assume the average person that gets into the balloon has a mass mp = 73.0 kg and volume Vp = 0.077 m3. How many FULL people can the balloon lift up? (Your answer must be an integer.)
