Can you find the orbital velocity of a planet which a satellite has to obtain in order to revolve around the planet with this formula:
v = [tex]\sqrt{\frac{Gm_E}{r_E}}[/tex]
G = gravitational constant 6.67*10-11
mE = Mass of a planet
rE = the radius of the orbit
rE = h + r
h = height of the orbit
r = the radius of a plant from the center of the planet to its surface
Lets see, if you want to find the orbital velocity that a satellite has to get in order to orbit the Earth in Low Earth Orbit (346.9 km).
mE = 5.98*1024 kg
rE = h + r
h = 346,900 meters (346.9 km)
r = 6.38*106 meters
v = [tex]\sqrt{\frac{(6.67*10^-^1^1)(5.98*10^2^4 kg))}{6,726,900}}[/tex]
v = 7,700.27 m/s
In order to obtain an orbit at an altitude of 346.9 km you will need to get a velocity of 7,700.27 m/s. Is this right, if not please correct me. Thank you for your time.
