**1. Homework Statement**

I'm writing a paper on the Manhattan Project, and as part of this paper I am asked to show:

"... calculations that can help illustrate the explosive power of an atomic bomb compared to ordinary explosives."

**2. Homework Equations**

Released energy per fission:

Q = [tex]\Delta[/tex]m * c

^{2}

**3. The Attempt at a Solution**

I'm pretty sure I know how to do this. I just need to find a reliable source (e.g. not wikipedia) and find out how many fissions actually happened in the first atomic bombs (Little Boy and Fat Man), then multiply that amount by Q. Just want to make sure this is the proper way to do this. I figured I'd look up the yield for TNT, too, and then compare the energy released by the atomic bomb to an amount of TNT with equivalent energy.

Does anyone know where I might be able to find the amount of uranium, maybe even the enrichment level of it, used in Little Boy, and the same specifications for Fat man, along with the amount of each substance actually converted into energy during the explosion?

Thanks in advance
