Let C be the straight line curve between the points (0, 9) and (1, 0). Let N be the unit normal vector field on C, oriented so that it points away from the origin. Let F : R2 > R2 be the vector field defined by F(m7 y) = (m, 17). Find the flux of F across the curve C in the direction pointing away from the origin. fOF - N ds =
