Problem

A space probe is launched vertically from the Earth’s surface with a speed of

9.0\,\text{km s}^{-1}

. Neglecting air resistance, determine the maximum height it will reach above the Earth’s surface before momentarily coming to rest. Data:

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

v_{e\,\text{Earth}} = 11.2\,\text{km s}^{-1}
