    Finding the Right String Length for a Dropping Mass

    This is a high school assignment, so I think [hope] we're not dealing with lost quantities. EDIT: We made headway on the problem, air resistance is negligible. Are we correct in thinking that this equation applies? ΔE = 0 -½ k x² + m g (h + x) = 0

On the day of the drop we will be given the mass. We will use two springs that we already have...
