it\'s numerical methods question

please provide a step by step solution

The velocity v (m/s) of air flowing past a flat surface is measured at several distances y (m) away from the surface/ Determine the shear stress tau(N/m^2) at y= 0, 0.002 and 0.012 using Newton\'s viscosity law tau = mu dv/dy Assume a value of dynamic viscosity mu = 1.8x10^-5(N. s/m^2). In your calculations, maintain O(h^2)
