Does this velocity sound reasonable?

Homework Statement


The radius of the Earth is 6.86 e6 m and the mass of the earth is 5.98 e24kg. There is a satellite floating in space at a point where the earth's gravitational acceleration is 3.2 m/s^2.

What is the velocity of the satellite



Homework Equations


Possibly A cent = V^2/R
g = GM/R^2
Fg = GMm/R^2


The Attempt at a Solution


So I did 3.2 = GM/R^2....R = 1164480.51. Then I did Ac = V^2/R. And solved for V^2. I got 1930 m/s. Does this sound like a reasonable velocity for a satellite?

You miscalculated the magnitude of R.
