#### HW # 5

Put a link here to an example problem you made up and solved using Laplace Transforms, of the complete solution of a mechanical system or a circuit that is described by linear ordinary differential equations with constant coefficients. Make sure you start with the physical system, and end up with the time response of the system.

Use your wiki page to explain the problem and solution to one of your classmates. Have him or her certify that they have checked it for errors, by listing that on the page. Then go to Moodle and put a link to your page in the in-box for HW #5.
