Problem
Two satellites S1 and S2 revolve round a planet in coplanar circular orbits in the same sense. Their periods of revolution are 1 hour and 8 hours respectively. The radius of the orbit of S1 is 104 km. When S2 is closest to S1 , find
(i) the speed of S2 relative to S1 ,
(ii) the angular speed of S2 as actually observed by an astronaut in S1 .
