Although it seems that the consensus is that Cal is better for undergraduate physics than UCSD, I'm wondering how substantial this difference might be. Several factors (mostly money) make it more convenient for me to live at home and go to UCSD for physics, but this could be dealt with if there...
Homework Statement
A stone is thrown straight upward with a velocity of 10V and travels upward a distance X. What is the displacement when the object is traveling at 5V?
Homework Equations
xf=x0+v0t+1/2at^2
vf=v0+at
vf^2=v0^2+2ax
The Attempt at a Solution
.75X? Further...
Sorry, I still don't totally understand the first identity. How do you derive that? There isn't a scalar product, so is some other operation implicit?
Also, (this is going to be a stupid question) but |\phij><\phij| cannot be simplified, right?Lastly, can you commute the bra and the ket to form...
Concerning expectation values...
Also, the derivation in terms of bra-ket rather than wage function would be appreciated.
Where \psi is the system state
Knowing that <A>\psi=<\psi|A|\psi>
And A is comprised of a complete eigenvector set \phij w/ corresponding eigenvalues aj
How do you...
