If Felix Baumgartner used a regular helium balloon to lift up to space in the Red Bull Stratos capsule (weight = 13,328 N), how many balloons would he need?
Assuming the average lifting force of a helium balloon is around 100 N, Felix Baumgartner would need approximately 133 balloons to lift the Red Bull Stratos capsule weighing 13,328 N.
