Calculate the speed of a satellite moving in a stable circular orbit about the earth at a height of 4800 km

The speed of satellite or orbital speed is given by below formula.

V = sqrt (GM/R)

where

G = is the gravitational force

M = earth's mass

R = radius of its orbit.

Solving for the Orbital Speed,

First add the earth's radius to the height of satellite wrt to the earths surface, we have R = 6.59x10^6 m + 4.8 x 10 6 m = 11.39x10^6

Now

V = sqrt ((6.673 x 10-11*5.98x1024 kg)/11.39) =5919 m/s

1= 26.17

2= 1.17

3=30.86

4=5.86
