A satellite is orbiting at 3000Km above the equator so that's it's angular velocity is the same as Earths. Assuming the Earth to be a sphere of radius 6400Km, estimate the linear velocity of the satellite relative to the centre of the Earth given that the Earth rotates exactly once every 24 hours.
The Attempt at a Solution
This is a problem someone asked me to help with but it's been so long since i was in college i'm finding it hard to remember what equations i should be going for.
Can anyone give me the equations i would need to solve this problem?
