On October 21, 2001, Ian Ashpole of the United Kingdom achieved a record altitude of 3.35 km (11,000 ft) powered by 600 toy balloons filled with helium. Each filled balloon had a radius of about 0.47 m and an estimated mass of 0.32 kg. (a) Estimate the total buoyant force on the 600 balloons. (Enter your answer to at least two decimal places.) kN(b) Estimate the net upward force on all 600 balloons. kN(c) Ashpole parachuted to Earth after the balloons began to burst at the high altitude and the system lost buoyancy. Why did the balloons burst? Atmospheric pressure at this high or low altitude is much lower or higher than at the Earth's surface.
The pilot of a Boeing 767 determines that a total of 22,300 kilograms of jet fuel is needed to fly from Montreal to Edmonton.
