(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two identical satellites orbit the earth in stable orbits. One satellite orbits with a speedvat a distancerfrom the center of the earth. The second satellite travels at a speed that is less thanv. At what distance from the center of the earth does the second satellite orbit?

2. Relevant equations

a = (v)^2/r

F = m/a

F = G (M * m )/ r^2

3. The attempt at a solution

I'm really confused on how to manipulate these equations.

Ultimately, I need to find an equation that relates "r" to "v."

r = a * v^2

So if the second satellite is moving slower doesn't that mean "r" has to be bigger? This makes me think of one of Kepler's Laws.
