Potential energy. Kinetic energy is movment
Given:
Radius of earth,
Radius of of orbit,
mass of earth,
Formula used:
By Kepler's third law,
Solution:
Using the given values in above mentioned formula:
Therefore, time period of satellite is
Power = exactly (current) times (voltage)
Power = exactly (about 2 A) times (240 volts)
Power = about 480 watts
That is an Elastic collision
