A vector has an x-component of - 7.55m and a y-component of - 2.48. Find the magnitude of the vector

A crude approximation for the x component of velocity in an incompressible laminar boundary layer is a linear variation from u = 0 at the surface (y = 0) to the freestream velocity, U, at the boundary-layer edge (y = δ).
