2. A Newtonian fluid having a specific gravity of 0.92 and a kinematic viscosity of 4x10-4 m²/s flows past a fixed surface. Due to the no-slip condition, the velocity at the fixed surface is zero and the velocity profile near the surface is shown in the following equation. Determine the magnitude and direction of the shearing stress developed on the plate. Express your answers in terms of U and 6, with U and 6 expressed in units of m/s and m respectively.
