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 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?

Constants Part C Hot air balloons float in the air because of the difference in density between cold and hot air. Consider a balloon in which the mass of the pilot basket together with the mass of the balloon fabric and other equipment is mb. The volume of the hot air inside the balloon is Vi and the volume of the basket, fabric, and other equipment is V2. The absolute temperature of the cold air outside the balloon is T...

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...

The mass of a hot-air balloon and its cargo (not including the air inside) is 200 kg. The air outside is at 10.0°C and 101 kPa. The volume of the balloon is475 m3. To what temperature must the air in the balloon be heated before the balloon will liftoff? (Air density at 10.0°C is 1.25 kg/m3.) 1 K

A recreational (open) hot air spherical balloon has a radius of 7.30 m when fully inflated. The total weight of the balloon, basket, ballast and pilot is 1710 N. When the balloon is released from its mooring, it moves upward and reached a terminal velocity of VT = 0.910 m/s. If the air resistance is given by Fair resistance = b VTwhere b = 2570 kg/s, what is the density in the hot air in the balloon? The density of...

A hot air balloon starts to take off when the temperature inside the balloon is 111 °C higher than the outside air. The pressure is the same inside and outside the balloon and there is a total of 2.50× 105 moles of air in the balloon. Assuming that the air density outside of the balloon is 1.20 kg/m3, what is the total mass of the balloon and its load? The answer is 2.73 × 103 kg. I am not sure...

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.
