A satellite of mass 500kg is launched into a circular orbit at an altitude of 600km above the Earth’s surface. Take Earth’s radius RE=6.4×106m and GME=3.986×1014Nm2/kg.
(i) Determine the orbital radius of the satellite measured from the centre of the Earth.
(ii) Calculate its orbital speed.
(iii) Compute the time period of revolution around the Earth.
