Problem

Mars has mass

6.4\times10^{23}\,\text{kg}

and radius

3.4\times10^{6}\,\text{m}

. Calculate the minimum speed with which a rocket must be launched from its surface, neglecting atmospheric resistance, so that it can escape Mars’s gravitational field.

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