# Calculating energy of a geosynchronous satellite

## Homework Statement

--------------------------------------------------------------------------------

hey i was just wondering if i was on the right track here, the question is calculate the total energy(E) of a geosynchronous satelite (that orbits around a fixed spot) with a mass of 1500kg orbiting earth at a height of 325km with an orbital speed of 5000 m/s,

## Homework Equations

ok i was taught that Total E = Kinetic E + Potential E, and also that Kinetic E= 1/2mV^2 and Potential E= mgH

## The Attempt at a Solution

ok i took into account that gravity would not be 9.8 so
i calculated what it would be Using Fg=Gm1m2/d^2 and i came up with 1.32x10^4,also note that to calculate distace i added 325km to the radius of the earth, then i plugged
in 1/2(1500)(5000)^2 + 1.32x10^4(1500)325000 = Total E, does this seem correct? thanks
