ok well, i think i should use the equation Fg = Gmm over r^2 but i don't know how to find the other mass. and the radius of the satellite.

Here's the question. I'm not sure how to apporoach it. A satellite has an orbital speed of 4.2 x 10 exponent 3 m/s. What is the altitude above Earth's surface? (M of Earth = 5.98 x 10 exponent 24 kg, radius of Earth = 6.38 x 10 exponent 6 m)
