A satellite is designed to orbit Earth at an alltitude above its surface that will place it in a gravitational field with a strength of 4.5 N/m.

            a)        Calculate the distance above the surface of the Earth at which the satellite must orbit.

            b)        Assuming the orbit is circular, calculate the acceleration of the satellite and its direction.

c)         At what speed must the satellite travel in order to maintain this orbit
