the space shuttle typically orbits 400 km above the earth's surface.the earth hass a mass of 5.98*10 to the 24 squared kg and a raduis of 6,380 km.A)how much would a 2000 kg part form the space station weight 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 spedd of the shuttle's cargo.
