Find (p,t) for the free particle in terms of the function (k) introduced in Equation

Question:

Find ϕ (p,t) for the free particle in terms of the function ϕ (k) introduced in Equation 2.101. Show that for the free particle |ϕ (p,t)|2 is independent of time. The time independence of |ϕ (p,t)|2 for the free particle is a manifestation of momentum conservation in this system.

Equation 2.101
