Apackage of mass 5 kg sits on an airless asteroid of mass 7.6 × 1020 kg and radius 8.0 × 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 170 m/s. we have a large and powerful spring whose stiffness is 2.8 × 105 n/m. how much must we compress the spring?
