Question

I can't figure any of this out, please help me?!

The International Space Station (ISS) just celebrated its 10th anniversary of human habitation. During that time it has been orbiting the earth at an altitude of 350 Km.

a. If the radius of the earth is 6,370 Km, what is the period of orbit for the ISS?
b. Does the orbiting speed of the ISS depend on its mass?
c. Suppose the ISS is in a stable orbit when the space shuttle brings in a new component for attachment. This increases the mass of the ISS. Do the astronauts have to adjust the speed of the shuttle to maintain the same orbit? (hint: momentum is always a factor in our universe) Explain your reason for your answer.
d. If the ISS were to be moved to a geosynchronous orbit (always staying above the same point on the earth), What would the new altitude of the ISS have to be?

Explanation / Answer

gravitational force GMm/r2 = mv2/r let mv2/r = m?2r and now let this equal to the grav force. then ? = 2?/T and you get a value for T.
