System of N classical anharmonic 3d oscillators

[issler]

1. Calculate the internal energy of a system of N classical anharmonic tridimensional oscillators of potential energy V(r) = k*(r^a) with k>0 a>0 and r = abs(r). Verify the result with a = 2 .

Would be nice if you give a little more information like the thread at the beginning of these forums states. I would suggest reading that, coming back, and editing your post so I have more of an idea of what you want answered. For example...are you using the potential energy function

$$x(U) = \frac{1}{2\pi \sqrt{2m}} \int_0^U \frac{T(E)dE}{\sqrt{U-E}}$$?
