1. The problem statement, all variables and given/known data Recall that the spring constant is inversely proportional to the number of coils in the spring, or that shorter springs equate to stiffer springs. An object is attached to the lower end of a 14-coil spring that is hanging from the ceiling. The spring stretches by 0.160 m. The spring is then cut into two identical springs of 7 coils each. Each spring is attached between the ceiling and the object. By how much does each spring stretch? 2. Relevant equations F = -kx 3. The attempt at a solution I don't remember an equation that involves the number of coils related to the k value or the distance it stretches. I thought if you cut the spring in half that they'll each stretch to half of the distance. I dont know if thats true. Help is appreciated.
