A hot air balloon consists of a basket hanging beneath a large envelope filled with hot air. A typical hot air balloon has a total mass of 529 kg, including passengers in its basket, and holds 2.59 X 10 m of hot air in its envelope. If the ambient air density is 1.26 kg/m?, determine the density (in kg/m) of hot air inside the envelope when the balloon is neutrally buoyant. Neglect the volume of air displaced by the basket...
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 = 4.8 m. The total mass of the empty balloon and basket is mb = 120 kg and the total volume is Vb = 0.068 m3. Assume the average person that gets into the balloon has a mass mp = 71 kg...

A hot-air balloon is accelerating upward under the influence of two forces, its weight and the buoyant force. For simplicity, consider the weight to be only that of the hot air within the balloon, thus ignoring the balloon fabric and the basket. The hot air inside the balloon has a density of ρhot air = 0.76 kg/m3, and the density of the cool air outside is ρcool air = 1.29 kg/m3. What is the acceleration of the rising balloon?
A hot-air balloon is accelerating upward under the influence of two forces, its weight and the buoyant force. For simplicity, consider the weight to be only that of the hot air within the balloon, thus ignoring the balloon fabric and the basket. The hot air inside the balloon has a density of ρhot air = 0.95 kg/m3, and the density of the cool air outside is ρcool air = 1.29 kg/m3. What is the acceleration of the rising balloon?
A balloon inflated with helium
gas (density = 0.2 kg/m3) has a volume of 6 × 10–3 m3. If the
density of air is 1.3 kg/m3, what is the buoyant force exerted on
the balloon?

Consider a hot air balloon with a volume of 1,500 m3. As you may remember, it will float when its average density (including its payload) is less than the density of air. Suppose that the empty balloon plus its payload have a mass of 200 kg, and that the bottom neck of the balloon is open to the air, as shown in the picture. a) What is the density of air at room temperature at ground level? (Assume that, by...
Chapter 11, Problem 048 GO A hot air balloon is accelerating upward under the influence of two forces, its weight and the buoyant force. For simplicity, consider the weight to be only that of the hot air within the balloon, thus ignong the balloon fabric and the basket. The hot air inside the balloon has a density of Phot 0.90 kg/m, and the density of the cool routside Pool 1.29 kg/m. What is the acceleration of the ning balloon? Click...
b. A hot air balloon has a volume of 2000 m3 when fully inflated, and the air inside the balloon is always at atmospheric pressure because of the large opening used to fill the balloon and heat the air inside it. What's the mass of hot air inside the balloon if its temperature is 120°C? (Assume a molecular weight of 28.8 g/mole for air.) 1790 kg 5850 kg 62.0 kg 203 kg
