A 1 036-kg satellite orbits the Earth at a constant altitude of 110-km. (a) How much energy must be added to the system to move the satellite into a circular orbit with altitude 194 km? MJ? (b) What is the change in the system's kinetic energy? MJ? (c) What is the change in the system's potential energy? MJ?
Mass of the satellite m=1036 kg
Altitude of the satellite
Total energy of the satellite in a orbit of radius r, from
thecenter of the Earth is
Hence energy of the satellite at
And the energy of the satellite at
is
Hence energy needed to be added to the system to move the
satellitefrom
