The space shuttle Endeavour, with mass 86,400 kg, is in a circular orbit of radius 6.66 X 106 m around the earth. It takes 90.1 min for the shuttle to complete each orbit. On a repair mission, the shuttle is cautiously moving 1.00 m closer to a disabled satellite every 3.00 s. Calculate the shuttle's kinetic energy
(a) Relative to the earth and
(b) Relative to the satellite.
