To circle Earth in low orbit, a satellite must have a

speed of about 2.7 X 104 km/h. Suppose that two such satellites orbit

Earth in opposite directions. (a) What is their relative speed

as they pass, according to the classical Galilean velocity transformation

equation? (b) What fractional error do you make in (a) by

not using the (correct) relativistic transformation equation?
