Problem

A satellite of mass

500\,\text{kg}

is launched into a circular orbit at an altitude of

600\,\text{km}

above the Earth’s surface. Take Earth’s radius

R_E = 6.4\times10^{6}\,\text{m}

and

GM_E = 3.986\times10^{14}\,\text{N\,m}^2\!\text{/kg}

. a. (i) Determine the orbital radius of the satellite measured from the centre of the Earth. b. (ii) Calculate its orbital speed. c. (iii) Compute the time period of revolution around the Earth.
