The velocity distribution for flow over a flat surface is given by $u=\frac{3}{4}y-1\mathrm{.}8y^2$ in which

u is the velocity in $\frac{m}{s}$ at a distance y meter above the plate. Determine the shear stress

at $y=0,0\mathrm{.}01,$ and $0\mathrm{.}1$ m $.$ Take the dynamic viscosity of the fluid is $0\mathrm{.}97$ Pa$.$s
