A steady, incompressible, two-dimensional velocity field is given by V = (u, v) = (0.65+1.7x)i + (1.3-1.7y)j where the x- and y-coordinates are in meters and the magnitude of velocity is in m/s. The x- and y-component of material acceleration a_x and a_y at the point (x = 0 m, y = 0 m), respectively, in m/s^2, are
