Problem

An artificial satellite revolves around Earth at an altitude of

300\,\text{km}

above the surface. Given

G = 6.67\times10^{-11}\,\text{N m}^2\text{kg}^{-2}

, Earth’s mass

M_E = 5.97\times10^{24}\,\text{kg}

and Earth’s radius

R_E = 6.37\times10^{6}\,\text{m}

, calculate the orbital speed of the satellite.
