You want to check if these measurements are correct. You are going to use a
balloon and rise in the corresponding altitudes. If the balloon weighs 1000kg
(all included, weight of yourself, equipment, inflated part etc) calculate the
volume of inflated part of the balloon, so that the initial acceleration is
15m/s?. Assume that the balloon is a sphere and neglect the deflated part of
the balloon as far as volume is concerned. Can you verify all measurements
with this volume of the balloon? What kind of adjustments do you need to
make in order to complete your mission?
