1. The problem statement, all variables and given/known data A spring is stretched by a force of 0.80n a distance of 0.012m. Find how far it will stretch when the force is 0.54n. One problem is that I don't know how to find k. 2. Relevant equations F=kΔd 3. The attempt at a solution F=kΔd F=k(0.012m) What is k?
