Hey guys.. need this pret-ty bad....
1. Calculate a parking orbit angular velocity of a satellite, above Earth, at an altitude of 400km above sea level
2.
Calculate the time needed to move from the parking orbit (above) to a geostationary orbit.
3.
Calculate the change in velocity needed to move form the parking orbit to the geostationary orbit.
4.
Calculate how long it will take for a space ship to move from a parking orbit to hit the oceans surface.
and heres the first question which I can do... but it may help you...
The Lockheed X-33 launcher has a dry mass of 34000kg and carries 9800kg of liquid fuel. Its engine develops a thrust of 1000kN, which increases with altitude and burn for 100 s, during which 98000kg of fuel is burnt.
so yeaa.. help please
