Question

What is the gpe of a 200 kg hot air ballon 21,000 m above the ground?

Answer 1

gravitational Potential energy is given by

`GPE = mgh`

here we have

m = 200 kg

h = 21000 m

now we will have

`GPE = 200(9.8)(21000)`

`GPE = 4.116 * 10^7 J`

so GPE of balloon will be 41160000 J above the given height from ground
