Problem 2.4 in Griffiths

Also additional problem:

Johnson 3.1 Let y(x) = A x exp( -ax) for 0 £ x and = 0 for x < 0. Find A so that the wavefunction is normalized. Compute < x >, < x² >, < p >, < p² > and the corresponding uncertainties in x and p. Does this wavefunction satisfy the uncertainty principle?
