The space shuttle typically orbits 400 kilometers above the earth's surface. The earth has a mass of 5.98 × 1024 kilogram and a radius of 6,380 kilometer.
A) Find how much would a 2000 kilogram part for the space station weigh when it has been lifted to that orbit in the shuttle's cargo bay?
B) Find the acceleration due to gravity at that altitude?
C) Use your knowledge of gravitation to compute the orbital speed of the shuttle cargo.
