Hi, I've attached the problem as a Picture. I've learned a lot from the help I have received here on Brainmass, and I'm going to try doing this one on myself and hopefully I'll do it right. Thank you for your help!

Consider a simple harmonic oscillator with an angular frequency w. Suppose at t=0 it is in a state given by: (see attachment for equation)
a. Find the normalization constant N
b. What are the possible outcomes of an energy measurement? What are the probabilities associated with each of these outcomes?
c. How does this state evolve in time? In other words find v,t>
d. Find < x > (t) and <p> (t), i.e. find how the average position and momentum changes as a function of time.

States of a Quantum Harmonic Oscillator

6. Consider the state of a harmonic oscillator initially (t=0) to be given by |phi >= 5|0 + 12| 1>.
(a) Find the normalized state.
(b) What will be the state of the particle after time t.
(c) Calculate < x > and < p > for this state at time t. Is this classically what you would expect?
