Two satellites are in circular orbits around the earth. The orbit for satellite A is at a height of 418 km above the earth’s surface, while that for satellite B is at a height of 731 km. Find the orbital speed for (a) satellite A and (b) satellite B.

Answer 1

consider cetnripetal acceleration =graviational
v1^2/(re+418) = g*(re/(re+418))^2

solve for v1, then do the same for v2
