Homework Help: How to find the average potential energy given V(x,y) and E?

  1. Jan 12, 2017 #1
    1. The problem statement, all variables and given/known data
    A classical particle with total energy E moves under the influence of a potential V(x,y) = 3x3+2x2y+2xy2+y3. What is the average potential energy, calculated over a long time?

    2. Relevant equations

    3. The attempt at a solution
    I think that this can be solved using Virial Theorem but I am unable to apply the standard form 2T = nV. What is the value of n here?

    Perhaps I'm being too simplistic, but I note that the potential function has no lower bound and no local minima, so....
