Asked by Julie

I have a question about the International Space Station-Its been orbiting earth at 350km-If the radius of the earth is 6,370 km, what is the period of orbit for the Space Station?

Secondly, if it was moved to a geosynchronous orbit, what would the new altitude of the station be?

If youcould just direct me or give me a clue how to solve these, I would appreciate it. I think something is missing from these questions in order to solve them. If you could even verify that, I'd appreciate it

Thank you

No, you have all you need.

consider centripetal force, that has to equal gravity.

GMe*m/(re+h)^2=m w^2(re+h)

w= Find w. Then, w=2PI/Period, solve for period.

For the geosynchronous orbit, you know period, find angular veloicty in radians/sec, and then find h.

Thank you-I'll try it and get back with a possible answer maybe tomorrow
