A 5450 m3 blimp circles Busch Stadium during the World Series, suspended in the earth’s 1.21 kg/m3 atmosphere. The density of the helium in the blimp is 0.178 kg/m3. a) What is the buoyant force that suspends the blimp in the air? b) How does this buoyant force compare to the blimp’s weight? c) How much weight, in addition to the helium, can the blimp carry and still continue to maintain a constant altitude?
