Calculate the work that must be done by a rocket engine to lift a

500\,\text{kg}

satellite from the Earth’s surface to a circular parking orbit

600\,\text{km}

above the surface. Neglect atmospheric drag. Take

R_{\oplus}=6.4\times10^{6}\,\text{m}

M_{\oplus}=6.0\times10^{24}\,\text{kg}

and

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