- Homework Statement
- The figure on the right shows a stratospheric balloon

carrying a payload. The density of helium at 1.0 atm and 15 oC

is 0.168 kg/m3 and the density for air is 1.225 kg/m3. The mass

of the balloon (skin without helium) and the payload is 260 kg.

The volume of the balloon at ground level is 300 m3

- Relevant Equations
- Upthrust?

I have gathered the formula:

F(Bouyant force) - (Mballoon + Mpayload)g - (Mhelium)g = (Mballoon + Mhelium + Mpayload)a

But i can't seem to figure out what is the buoyant force to find a. Or am i mistaking something?
