$2.[1$ point$]$ In class we solved for the velocity profile of flow between two fixed, horizontal, infinite parallel plates. Consider a similar scenario in which one of the plates is fixed while the other is moving at a constant velocity, $\backslash ($ U $\backslash )($see figure below$).$ Obtain the solution for the velocity in $\backslash ($ x $\backslash )-$direction. Assume a steady, fully developed, Newtonian and incompressible fluid.
