A space probe far from the Earth is travelling at \(14.8\,\text{km s}^{-1}\). It has mass \(1\,312\,\text{kg}\). The probe fires its rockets to give a constant thrust of \(156\,\text{kN}\) for \(220.\,\text{s}\). It accelerates in the same direction as its initial velocity. In this time it burns \(150.\,\text{kg}\) of fuel.

Calculate the final speed of the space probe in \(\text{km s}^{-1}\).
