Impressive, it looks like someone else has seen a 3rd year physics course. I managed to shank this very problem on the test I took this morning.

I hate it when that happens. Must be why I never took 3rd year physics. Too busy frying my brain with Perl scripts.

Hey narf! ... yeah, I think I do smell that smoke.

I got lucky when I took that stuff. I was taking a physics course which covered SHM, an electrical engineering course which was about RLC circuits and a mechanical engineering course about dynamics of materials. They all revolved around the same formula below hehehe. My homework was almost interchangeable except each class felt that they had to use their own letters. EE's used resistance, inductance and capacitance. ME's used mass, spring constant and damping constant. And the phyisics guys... well they had their hands in everything. Sheez that was about 15 years ago and I still recognize that formula.

Funny thing is, second order differential equations like this didn't make sense to me until my mechanical engineering classes started using the spring-mass-damper analogy. That's when the usefulness of Laplace Transforms started showing their true colors. I have even had to apply diff. e.q. to the real world when I had to calculate the CO2 levels in a room at a given time with a given number of people.
