A satellite is designed to orbit Earth at an altitude above its surface that will place it in a gravitational field with a strength of 4.5 N/kg
a) Calculate the distance above the surface of Earth at which the satellite must orbit
b) Assuming the orbit is circular calculate the acceleration of the satellite and its direction
I have solved part a) using the equation: Fg = sqr of Gm/r^2
I also solved the accelaration of the satellite by first finding the velocity (v = sqr of Gm/r) and then the circular acceleration (Ac = V^2/r).
I am a bit confused as to what they are asking for with regards to direction. I could work out the curve I suppose though I do not recall what forumula I would use. Can someone point me in the right direction please?
Thanks
