Help me please

Consider a laminar boundary layer flow over a flat plate for which the velocity profile can be approx-
imated by, u/U = 2(y/8) – 2(y/8)³ + (y/8)4.
a. Show that this profile satisfies the appropriate boundary conditions.
b. Using the momentum integral relation, equ.
grate Tw(x) and obtain an expression for the drag coefficient, Cp, as a function of Rej, where l
is length of plate.
derive expressions for 8/x and Tw(x). Inte-
