Answer #1

How much gravitational potential energy must a 3140-kg satellite
acquire in order to attain a geosynchronous orbit?
The answer to the above question is 1.67x10^11 J.
How much kinetic energy must it gain? Note that because of the
rotation of the Earth on its axis, the satellite had a velocity of
467 m/s relative to the center of the Earth just before launch.
Doing a 1/2mv^2 doesn't get the correct answer. The law of
conservation of energy would state that...
