The formula for orbital speed v is    v=(G*Me/r)^1/2
Wher G= 6.67E-11,    Me= 6E24,    r= Re+h= 6.4E6+740000
putting values in the formula we get

v= 7486.7 m/s     or  v= 7.4867 km/s

The orbital speed of a satellite in a circular orbit 740 km above the surface of the earth is 7,483.2 m/s.

What is orbital speed satellites?

Orbital speed of satellites is the speed relative to the center of mass of the earth.

The orbital speed is calculated as follows;

[tex]V = \sqrt{\frac{Gm}{R + h} } \\\\[/tex]

where;

  • m is mass of Earth
  • G is universal gravitation
  • R is radius of Earth
  • h is height of the satellite above the earth surface

[tex]V = \sqrt{\frac{(6.67 \times 10^{-11} )(5.97 \times 10^{24})}{(6371 + 740) \times 10^3} } \\\\V = 7,483.2 \ m/s[/tex]
