Where F is the attractive force between 2 masses, m1 and m2, r is the distance between the centres of the masses and G is the universal gravitation constant, which is 
The mass of the earth (
) is far greater than the mass of the sputnik (
). Therefore 
. The mass of the sputnik is neglected, therefore:
But F is actually centripetal acceleration, a = v²/r
