On October 21, 2001, lan 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 0.26 kg. (a) Estimate the total buoyant force on the 600 balloons. (Enter your answer to at least two decimal places.) 3298.7486 x kN (b) Estimate the net upward force on all 600 bailoons. x 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 altitude is much lower than at the Earth's surface.
