Calculate the velocity of a satellite moving in a stable circular orbit about the Earth at a height of 2600 km.

Answer 1

assuming Newtons law of gravity...

Force=mv^2/r
GMe m/(r^2)

GMe/r=v^2

where r=re+altidtude

Answer 2

v^2 = GM/r = 6.67*10^-11 * 5.97*10^24 / ((6371+2300)*1000) = 4.59*10^10

v = 6.776 km/s

Answer 3

typo - v^2 = 4.59*10^7
