I'm writing a book and I have a question about the effects of a fast moving object on an air mass. Strictly speaking, I am wondering how to compute the effects of a human-sized (70 kilo, roughly,) object moving in excess of 30,000 miles an hour on a hypothetical mass. I'm recently out of college and I have a passing knowledge of physics: AP physics in high school, dad was a physics prof, so I understand general theory, I'm just vastly out of practice. If someone could point me in the right direction vis a vis formulas/what to keep in mind when trying to work on a problem like this, it would be greatly appreciated. By the way, it's entirely possible based on my limited ability that I have missed a variable of some kind. Thanks.
