A satellite experiences a gravitiational force of 228N at an altitude of 4.0 x 10^7m above the earth. What is the mass of the satellite?
I do 228 = GMm/(4x10^7 x 6x10^6)^2 (and solving for m) and that's not the right answer.... so what should I be doing?

Ohh... I wrote in the bottom as D and R multiplying but that was just a typo.. i HAVE actually been adding them

F=G Mm/(D+R)^2
R= 6.38 x 10^6 m
D=4 x 10^7m
You are in error by multiplying while you have to add the radius of the Earth and the value of the altitude.
have fun

You are taking R as 4.0 x 10^7m whereas it should be 4.0 x 10^7m + radius of earth.(6 x 10^6 metres)
okay if ur still not getting the correct answer it's just a calculation mistake on ur side :)
Note - Mass of earth = 6 x 10^24 kg
