Answer:
The work done is calculated as
Solution:
As per the question:
Mass of the spaceship, m = 3500 kg
Height of the orbit, h = 220 km
Mass of the earth,
Height of the higher orbit, h' = 360 km
Radius of the orbit,
Now,
The work done is given by the change in the gravitational potential energy:
Gravitational Potential Energy, U =
Now, for the lower orbit:
For upper orbit:
Change in the gravitational Potential energy:
Therefore, the work done:
