a satelitte is in orbit about the earth. its orbital radius 7.47x10^7. mass of satelitte 6862kg & mass of earth 5.97x10^24kg determine the orbital speed in mi/s 1mi/s=1609m/s

What are the dimensions for your orbit radius? km? miles? meters?
Whatever it is, solve this equation for V
V^2/R = G*M/R^2
G is the universal constant of gravity and M is the mass of the Earth.
Then do the conversion from meters/s to miles/s
