Finish elastic collision ramp problem from class

1. Consider a typical force law for a sprng: F = k x

In this equation, x is displacement and k is a constant associated with how stiff the spring is (the opposite of how stretching it is)

Derive an expression for the work to stretch an "ideal" spring (one represented by the equation above). Note that this will also give you an expression for the energy stored in the stretched (or compressed) spring.
