Escape from Planet Earth

Score: 2 Points

Suppose, you want to spend some days somewhere outside the Planet you live. You have chosen a massive planet named Earth for spending some nice moments. At the end of your vacation, you want to come back home. During the flight, your altitude is $h$ above the surface of Earth, and your velocity at the $h$ altitude is $5\frac{km}{s}$. The escape velocity is $3\frac{km}{s}$ from the h altitude. What will be your speed at very very far from the planet Earth?

Assume that you have lost your way back home.
