Review Conceptual Example 2 as an aid in solving this problem. An object is attached to the lower end of a 100-coil spring that is hanging fromthe ceiling. The spring stretches by 0.172 m. The spring is then cut into two identical springs of 50 coils each. As the drawingshows, each spring is attached between the ceiling and the object.By how much does each spring stretch?
