1. The problem statement, all variables and given/known data A package of mass 9 kg sits at the equator of an airless asteroid of mass 6.1 * 10^5 kg and radius 36 m, which is spinning so that a point on the equator is moving with speed 2 m/s. 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 189 m/s. We have a large and powerful spring whose stiffness is 1.1*10^5 N/m. How much must we compress the spring? 2. Relevant equations Kp,f = Kp,i + Ui + W 3. The attempt at a solution Im kinda lost at how to attempt this problem so any help explaining me through the process would be great.
