Find the work to lift the rocket in Problem 9 from …

Find the work to lift the rocket in Problem 9 from $x = 6400$ out to $x = \infty$ . If this work equals the original kinetic energy $\frac{1}{2} m v^{2}$ , what was the original $v$ (the escape velocity)?

This exercise builds on another exercise in its source book, which isn't shown here.
