A satellite of mass 500 kg is revolving around the earth. At any instant the speed of satellite is 40 m/s . Consider all the cases at same instant(K=1000). What is the kinetic and potential energy of the satellite

The formula for Kinetic Energy of the satellite = 1/2 m v² = 1/2 * 500 * 40² Joules
KE = 400 KJ
The formulas of KE and PE for a satellite give us that :
PE of a satellite = - 2 * Kinetic energy = - 800 KJ
The total energy of satellite is = - 400 KJ.
Negative energy means that the satellite is bound with an attractive force (of gravitation).
KE = 400 KJ
