Answer: The total net force acting on the balloon is 3457.86 N.
Explanation: The total net force on the balloon can be calculated as the difference between the buoyant force and the weight of the balloon:
Buoyant force = Weight of displaced air = Volume of displaced air x Density of air x g
Weight of balloon = Mass of balloon x g
where g is the acceleration due to gravity.
Using the given values, we can calculate:
Buoyant force = 2210 m^3 x (1.29 kg/m^3 - 1.13 kg/m^3) x 9.81 m/s^2
= 5812.26 N
Weight of balloon = 240 kg x 9.81 m/s^2
= 2354.4 N
Total net force = Buoyant force - Weight of balloon
= 5812.26 N - 2354.4 N
= 3457.86 N
