Does anyone know any good cites that will help me answer the following questions. "Is there a distinct advantage to being taller in an 800m race? 5000m race? If they both run the same exact time who does more work? Where and how is energy released to maintain the current work output?" I put all my eggs in one basket and got screwd big time. This is for an end of the year Physics project and we have to have permission from the cites we use. And well to make a long story short the cite I went to use for my main chunk of facts and data are not replying. This project is due on the 13th (2 days) and I really dont want to B.S. something I really want to do well on. So please if anyone knows any cites that may help please do tell. I am royally screwd! Thanks in advance.
