Homework Statement
How far above the surface of the moon should a satellite be placed so that it is stationary with respect tot the moons surface.
Radius of moon = 1737.4 kilometers
mass of moon = 7.36 x 10^22 kilograms
Gravitational Constant = 6.67 x 10^ -11 N x m^2/kg6@
Homework Equations
w = 2pi / T = 2pi/ 2332800 seconds (27 days/period of the moon)
v = w x Radius of satellite
(Ms) Vs^2/Rs = G Mm/Rs^2
Vs^2/Rs = (Gn) Mm/ Rs^2)
Mm = mass of moon
Rm = radius of moon
Ms = mass of satellite
Rs = Radius of satellite
etc...
The Attempt at a Solution
w = 2pi/ 233280 = 2.7 x 10^-6
