gravity is providing the centripetal force (keeping the satellite on a circular path)
a = v² / r
you have a and r, just make the units consistent (a to km OR r to m)
A satellite orbits the Earth with a radius of 7000km. The acceleration of gravity at this distance=8.17m/s/s.
How do I find the velocity of the satellite? I'm really struggling with finding the correct formula. I know the answer but can't figure out how to get there.
Thanks if anyone can help.

Sorry, I don't understatnd, and the answer doesnt compute to what is considered correct.
a=v^2/r where r is the distance from center Earth (re+altitude). solve for velocity
Thank you
