An elastic chord is 65cm long when a weight of 75N hangs from it, but is 85cm long when a weight of 180N hangs from it. What is the "spring" constant 'k' of this elastic chord?

The answer in the book is 5.3 x 10^2 N/m but I don't know why!

What is the difference between a displacement vs. time graph and a distance vs. time graph?

We did an experiment in physics where we dropped a ball and as it fell it marked a piece of paper 1/60s (60 times in a second) We circled every other dot created so we had two sets of data. (circled dots and non circled dots)

On the first set we measured the distance between each dot. (Dot one to dot three, then dot three to dot five, then dot five to dot seven, etc)

On the second set we started at dot one and measured how far it was to dot two. We then measured to dot four from dot one. Then from dot one to dot six and then dot one to dot eight, etc. (measuring how far from the release point basically)

So the first set of data is Displacement where the second set is distance. However, since they arent the same values, whats the difference between the displacement/time graph and the distance/time graph?

Thanks a lot.
