A spacecraft (mass = $720 \mathrm{~kg}$ ) traveling at $11.2\mathrm{\frac{km}{s}}$ in the + 𝑦 direction approaches Jupiter, which moves at $13.1\mathrm{\frac{km}{s}}$ in the - 𝑦 direction and has a mass of $1.90 \times 10^{27} \mathrm{~kg}$. During a gravity slingshot, the spacecraft curves around Jupiter, depicted by a dashed trajectory. Assuming only gravitational forces act and Jupiter's motion remains unaffected by the spacecraft, find the spacecraft's final speed after escaping Jupiter's gravity.
