A light spring with a spring constant of 107.0 N/m rests vertically on the table, as shown in (a) below. A 2.00 g balloon is filled with helium (0°C and 1 atm pressure) to a volume of 4.50 m3 and connected to the spring, causing the spring to stretch, as shown in (b) below. How much does the spring stretch when the system is in equilibrium. (The density of helium is 0.179 kg/m3. The magnitude of the spring force equals kΔx.)

Strato-lab was a 1950s project in which large balloons were used
to carry astronauts in training to the Earth's stratosphere. In one
flight, a balloon 38.5 m in diameter was used to lift a total
payload of 580 kg. Assume the volume of the balloon was filled with
helium gas of density 0.179 kg/m3. The air density was
1.20 kg/m3.
(a) What was the buoyant force acting on the Strato-lab balloon?
(Enter the magnitude.)
