10POINTS!! A satellite orbits Earth 350 km above Earth's surface. Calculate the free-fall acceleration at this altitude.

i'll give you an idea to answer it your own

To find altitude, subtract the radius of Mars from this number. Remember to always use the distance from the core of the planet in these calculations! The satellite in Mars geostationary orbit must be stationed 17005 Kilometers above the surface of the planet and it must be travelling at a speed of 1446 m/s .

Explanation:

The orbital speed can be found using v = SQRT(G*M/R). The R value (radius of orbit) is the earth's radius plus the height above the earth - in this case, 6.59 x 106 m. Substituting and solving yields a speed of 7780 m/s. 5.
