## Homework Statement

A satellite is orbiting an still planet, the farthest part of the orbit is at 200 km and the closest part at 100 km.

what would be the speed of the satellite at the closest part of the orbit at 100 km if the speed at the farthest part is 1 m/s?

## Homework Equations

L=mvr

## The Attempt at a Solution

I tried to apply conservation of momentum with which the result would be 0.5 m/s but I am not sure if this result is valid for its posible the planet acquires a rotation to keep conservation of momentum true, value I dot know how to obtain.

I was told to post this here though is not actually homework, I am already an engineer and finished already my studies but I still want to learn more
