A white dwarf is the leftover core of a lower mass star, such as the Sun. They can have a maximum mass of $1\mathrm{.}44$ Solar Masses but a radius slightly smaller than the Earth. Assuming a white dwarf just shy of this limit with a mass of $1\mathrm{.}40$ Solar Masses and a size $84\mathrm{.}6\%$ that of the Earth, what is the escape speed at the surface of the white dwarf? $($answer in km$/$s$)$
