Query: Uncertainty Relations and Wave Packets on the Quantum Plane   (2+2)-dimensional quantum mechanical q-phase space which is the semi-direct
product of the quantum plane E_q(2)/U(1) and its dual algebra e_q(2)/u(1) is
constructed. Commutation and the resulting uncertainty relations are studied.
``Quantum mechanical q-Hamiltonian'' of the motion over the quantum plane is
derived and the solution of the Schroedinger equation for the q-semiclassical
motion governed by the expectation value of that Hamiltonian is solved.
