A satellite is describing a circular orbit about the Earth with speed V. The satellite is separated into two pieces by explosive bolts which gave them an equal but opposite velocity, u, relative and tangential to the orbit of the original satellite. Find the two new orbits. (I initially thought the orbits would be the same as the original except one piece would be going in the opposite direction, however my professor said that it was incorrect) Please show all steps/reasoning.
