A satellites are placed in a circular orbit that is 2.90 × 10 ^6 m above the surface of the earth. What is the magnitude of the acceleration due to gravity at this distance?


not sure how to set this up...
 
If it's in orbit, it shouldn't be accelerating... it should be at constant velocity.
So 0.

(Discounting the eventual drop to Earth, which I guess would mean that it is slowly.... very slowly... accelerating toward Earth)

acceleration is not just a change in velocity, but a change in direction as well.

The force that pulls the sat down towards the earth, instead of it flying straight into space, is the acceleration.

I dont want the answer jonesy, just how to set it up, I dont have the mass of the sat so I cant calculate it that way... not sure where to go..
 
^^^ he does not know the mass only the distance.

For some reason this strikes me as a quick question if the satellite is just orbiting the earth with no acceleration other than the pull of gravity wouldn't the answer simple be 9.82m/s^2.

Or is it different since it is in space and not here on earth?

Just a thought to look at
