Learning Target IA3: I can set up and use integrals to solve applied work problems. 1. Note that Hooke's Law applies for compressing a spring, also. A spring supporting a railroad car has a natural length of 12 inches, and a force of 8000 pounds compresses it only inch. Find the work done compressing it from 12 to 9 inches. Hint: The answer is 6000 foot-pounds. Now show all the work to get there, and don't forget to convert from inch-pounds to foot-pounds.
