The Earths mass is 81.3 and radius is 3.7.

The spring on the Moon has stiffness k, relaxed length Lo, and at its maximum compression it has length Lo / 4. What should be the launch speed v; on Earth such that when the package is caught by the spring on the Moon, the package comes to rest when the spring is maximally compressed? Your answer should be expressed in terms of the variables known in the problem (m, M, R, k, Lo) and fundamental physical constants such as G. You do not need to simplify your final
