Homework Statement
Calculate the total energy of a geosynchronous satellite (one that orbits over a fixed spot)
with a mass of 1.5 x 10^3 kg, orbiting Earth st a height of 325 km with an orbital speed of 5.0 x 10^3 m/s.
Homework Equations
Ek = 1/2 mv^2
Ep = mgh
Fg = Gm1m2/r^2
or
PE = -Gm1m2/r
The Attempt at a Solution
Im wondering if a should find the force of gravity using Fg = Gm1m2/r^2 of the satellite and then plug that into Ep = mgh and add Ek = 1/2mv^2 (Ep + Ek = Et). OR if i need to use PE = -Gm1m2/r
