I came to doubt myself when "square of the velocity" was introduced, since I knew that the square of a sum is not the same as the sum of squares, so my calculation was thrown into a vector of despair.
I am not whom you seek, but the "v" is flow velocity relative to the object and my understanding (perhaps flawed) is that v squared in the equation is scalar. The magnitude of velocity component parallel to the bike's motion.
