The planet Mars has a mass of 6.39x1023 kilograms (kg) and a radius of 3390 kilometers (km). A satellite is in orbit around Mars, at a height of 2250 km above the surface. The satellite launches a package downwards towards Mars with an initial speed of 1.25 kilometers per second (km/s). How fast will the package be moving when it lands on Mars? Assume that mechanical energy is conserved. Give your answer in units of km/s.
