Given that,
Mass of a satellite, m = 500 kg
Speed of satellite in a circular orbit, v = 30 m/s
To find,
The potential energy of the satellite in its orbit.
Solution,
The sum of kinetic and potential energy equals total energy. So,
We know that,
Also,
So,
Put the values of m and v in above formula we get,
So, the potential energy of the satellite in its orbit is 450 kJ.
