A package of mass 8 kg sits at the equator of an airless asteroid of mass 6.0 1020 kg and radius 9.7 105 m. We want to launch the package in such a way that it will never come back, and when it is very far from the asteroid it will be traveling with speed 209 m/s. We have a large and powerful spring whose stiffness is 1.2 105 N/m. How much must we compress the spring
