I was driving and hit some debris in the road that rattled around under my car. And instantly there was a humming noise that started that intensifies with acceleration and when I get to about 2 or 3 rpm a rattling noise starts. I was wondering what it may be.

Check the exhaust system. Something may have come loose or apart. Also, use a rubber mallet and tap on the muffler and catalytic converter to see if there is anything loose as well as check heat shields.
