A free particle is represented by the plane wave function ψ (x, t) =A exp[i(1.58 X 1012× - 7.91 X 1016t)]. where SI units are understood. What are the particle’s momentum, kinetic energy, and mass? (Note: In nonrelativistic quantum mechanics, we ignore mass/internal energy, so the frequency is related to kinetic energy alone.)
