Homework Help: Schroedinger Equation Problem

  1. Nov 7, 2011 #1
    1. The problem statement, all variables and given/known data

    What would you expect for <p> and <p^2> for the ground state of the simple harmonic oscillator?

    2. Relevant equations
    Expectation value = <p> = integral psi* * (partial derivative with respect to x of psi) dx

    3. The attempt at a solution

    I have no idea.

    Think about the classical model and then use the theorem of Ehrenfest or the virial theorem to draw the required conclusion.
