Correct compression is 0.41
Explanation:
After jumping from 2m height on spring attached platform platform is compressed a distance x(let).
So work done by gravity on Jim is converted into spring potential energy.
k=8000 N/m
mass of Jim =50 kg



Solve this quadratic one solution is positive and other is negative.
positive one is our answer = 0.41 m
