Homework Statement


A satellite is revolving round the earth at a height of 600 Km. Find the speed of the
satellite and the time period of the satellite, if the radius of the earth is 6400 km, and
mass of the earth = 6*10^24 kg.


Homework Equations





The Attempt at a Solution



Well this is what i thought of till now...
we need to work out the time it takes to get round the earth..

6400/600 = 10.6666 (recurring). so 10 hours?.....opps

another look
velocity = distance /time...

is time = timeperiod... i'm confused .. lol help please

Why are you dividing the radius of the earth by the height of the satelite? Did you even think about what units you have?

What is the distance of the satellite from the center of the earth? What is the gravitational pull on the satellite at that height? What is the acceleration due to that pull? What angular speed does that correspond to?
