Solution Summary

With good explanations and full calculations, the problem is solved.

Solution Preview

There are several ways to approach a problem like this. Let's take it from a conservation of energy approach:

At first, just as the block touches the spring, it has a certain amount of energy, E1, composed of gravitational potential energy due to its height, and kinetic energy due to its downward velocity. Let's set the 0 point for potential ...
