[explodingbird]

Homework Statement

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

Homework Equations

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

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.
