Find how long of a cord needed to drop an egg from 14m to come within 5cm of the ground

We have determined a force deflection ratio for the cord given a .5m sample.

2. Relevant equations

what is x supposed to be here. Is it a number as I have or is it the mass or the height of the drop?

3. The attempt at a solution

if I plug this into the energy conservation equation I get a solution of x = .8440104689 I have no idea what this means if it is even what I am supposed to do at this point.

the PE for the cord is as follows, determined from integrating the force deflection equation.

25.04714286*x^7+122.3833333*x^6-206.5000000*x^5+123.8475000*x^4-37.43333333*x^3+7.890000000*x^2+.2133000000*x

4. Additional comments.

I am supposed to have a working model for class on Monday, but when I use the value for x I get an increasing length of cord for increasing mass, assuming the total mass of the egg and bag is going to be 70~100grams.
