- Homework Statement
- If a static load of mass 20kg extends an elastic rope by 0.8m, what is the maximum extension that a falling man of mass 70kg who jumps off a high cliff tied to this elastic rope would produce, given that the rope is 10m long?

- Relevant Equations
- F=kx, hence x should be F/k. Since k is constant in both cases, F(man)/F(load)=extension(man)/extension(load)

I found the ratio between the weight exerted by the 70kg man to the weight exerted by the 20kg load, and equated it to the ratio of maximum extension by the 70kg man to the extension by the load

Is this a right step to use, because the book didn’t give any answer nor solution which can help me know whether I’m doing the right thing, and if not, what’s the correct solution please
