You'll have to give more details than that. Also, what is Ω?

I can however tell you that you seem to be going in the wrong direction. You don't actually need |Ψ(t)>, but rather |ψ> at the different parts of the apparatus.

oh,
Ω, I put Sx in the above image. and do i really have to put | ψ>? I was worried about the problem all day... i need u're help oh god

I think that the conditions are not enough for the above problems.
 
So, what is the state of the spin, after coming out of the first SG apparatus?

In general, the value of the experiment, of course, does not come up with the quantized upper and lower lines?
 
Read the text of the problem. It should be pretty clear what is the state of the spin after coming out of the first SG as described in the problem.
