If the two springs in Exercise are compressed the same distance, on which spring is more work done: (a) spring 1, (b) spring 2, or (c) equal work on both Exercise
Two springs are identical except for their force constants, k 2 k 1. If the same force is used to stretch the springs, (a) spring 1 will be stretched farther than spring 2, (b) spring 2 will be stretched farther than spring 1, (c) both will be stretched the same distance.
