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