Calculate Satellite Velocity in Stable Orbit

[smaxemow]

Q.Calculate the velocity of a satellite moving in a stable circular orbit around the Earth at a height of 5200km.

A. I wasn't sure which formula to use on this problem is it Ac=(V^2)/r

Well I don't know what other information you have

But what provides the centripetal force needed to keep the satellite in the orbit?

Hi smaxemow ! Welcome to PF!

Simple answer: yes.

That gives you the acceleration.

And now you need to know the force …
