An elastic cord is 67.7 cm long when a weight of 58.7 N hangs from it and is 85.8 cm long when a weight of 88.1 N hangs froms it. What is te spring constant of this elastic cord?(adsbygoogle = window.adsbygoogle || []).push({});

how i know which is the long of the spring when it is in equilibrium to then calculate the sprin constant?...

or anyother help to solve this problem
