In a new lab experiment, you find the spring constant of a "good" and "bad" spring. The "bad" spring is exactly the same as the "good" spring, except that it has been permanently deformed by misuse. If you find the "good" spring to have a spring constant of 9.80 N/m and the "bad" spring to have a spring constant of 4.44 N/m, what was the percent change in the spring constant caused by deforming the spring?
