Quizplus · Accepted Answer

Segments A and C show a constant force acting in the opposite direction to the object's motion, which is a characteristic of a fixed spring. Segments B and D show the object being accelerated without any opposing force, which is not characteristic of a spring. Therefore, only segments A and C could represent work being done by fixed springs.
