the space shuttle typically orbits 400 km above the earths surface. The earth has a mass of 5.98 * 10^24 kg and a radius of 6380km.
A) How much would a 2000 kg part for the space station weigh when it has been lifted to that orbit in the shuttles cargo bay?
B)Use your result from Part A to determine the acceleration due to gravity at that altitude.
C) Use your knowledge of circular motion to determine the orbital speed of the shuttles cargo.

a. if the shuttle were in orbit, the 2000kg will weigh zero.
b. Maybe the part a was not interested in weight at all, but the gravitational attracation
W=GMe*2000/(6.380+.4)^2
That is the graviataional attraction,perhaps that is what the teacher wanted in part a.
Then part b would be
g'*2000=W so g'=W/2000
c. g'=V^2/(6.38+.4)^2 solve for V

I erred on units.
W=GMe*2000/(6.380E6+.4E6)^2
g'=V^2/(6.38E6+.4E6)^2 solve for V
W=GMe*2000/(6.380E6+.4E6)^2
g'=V^2/(6.38E6+.4E6)^2 solve for V
