TheInternational Space Station orbits the Earth at a height of 400kmabove the Earthâs surface. a) What is the speed of thestationrelative to the Earth center? b) Express its total energyin termsthe distance from the Earthâs surface without usingthe speed. (Anumerical value would require knowing thestationâs mass). As partof a publicity stunt, a Russiancosmonaut on the station decides todo an E.V.A. (Extra VehicularActivity) and play a little golf. Heâtees upâ andwacks the 0.05 kg golf ball at a velocity of 500 m/srelativeto the station, directly with the stationâsorbitingdirection. c) At what height above the Earthâs surfacewillthe ball eventually orbit? Assume that the total energy ofthegolf ball remains unchanged and that its final orbitisapproximately circular.
