A 500 kg weather balloon is designed to lift a 1600 kg package.

Question

A 500 kg weather balloon is designed to lift a 1600 kg package. Remember, Weight = mass * 9.8 and Density = [total mass]/[volume of water displaced]

 

1. What is the total mass of the balloon and the package?
2. What is the weight of the balloon and package together?
3. If the balloon is neutrally buoyant what is the buoyant force on the balloon/package?
4. What is the volume of a helium balloon if the density of helium is 1.2 Kg/L?

Answer 1

A 500 kg weather balloon is designed to lift a 1600 kg package. Remember, Weight = mass * 9.8 and Density = [total mass]/[volume of water displaced]

 

1. What is the total mass of the balloon and the package?
2. What is the weight of the balloon and package together?
3. If the balloon is neutrally buoyant what is the buoyant force on the balloon/package?
4. What is the volume of a helium balloon if the density of helium is 1.2 Kg/L?

Given Mass of balloon = 500 kg

Mass of package = 1600 kg

1.Total mass = 500+1600 =2100kg

2 Total weight = 2100*g= 2100*9.8 = 20580 N

3 Buoyant force = 20580 N

4 As density = Mass /volume

Volume of balloon = mass/ density = 500/1.2 L
