Calculate d<p>/dt Answer: d<p>/dt = <-dV/dx>
generally speaking (I believe) you need to use scrodinger's equation (both of dphi/dt and dphi*/dt)
and the expectation value of momentum:
<p> = -i*h_bar * integral (phi* * dphi/dx) dx.
I would say that the way I used Cramster was just short of plagiarism because I really don't know what I'm doing with this problem. I don't believe we are supposed to use Hamiltonian to prove this problem because the book won't get to them 'till chapter 2.
The proof took about 1.5 pages and didn't even seem conclusive at the end. Could someone please just provide a general explanation of how this was solved?
I used Cramster already to answer this question (odd number so it's free to view with an account):
