Calculate the probablity density and current density of a wavefunction

[anchal2147]

Homework Statement

Want to find the solution of part b,c and d

Relevant Equations

time evolution operator, momentum and position operator

i have use time evolution operator to get the wavefunction at any time "t" as Ψ(x,t) = U(t,t1) * Ψ(x,t1)
but i don't know how to calculate next part of the question

Maybe it helps to enlarge your list of "relevant equations" by the probabilities asked for in (b) and for the probability density and current density in (c)...
