Infinitesimal velocity-dependent symmetry mappings of second-order dynamical systems (a) E/sup i/(x, x, x, t)equivalentx/sup i/ -F/sup i/(x, x, t) = 0, i = 1,..., n, were studied in considerable detail in a previous paper (J. Math. Phys. 2X, xxxx (198X), the first of this series). Among the results developed in that paper was a procedure for determining the characteristic functional structure of symmetry mappings for such second-order systems. In this present companion paper it is shown that a similar procedure may be used to obtain the characteristic functional structure of infinitesimal symmetry mappings (b) y-bar/sup I/ = y/sup I/+deltay/sup I/, deltay/sup I/ equivalenteta/sup I/(y, t)deltaa; (c) t-bar = t+deltat, deltatequivalenteta/sup 0/(y, t)deltaa, for systems of first-order differential equations (d) E/sup I/(y, y, t)equivalenty/sup I/-lambda/sup I/ (y, t) = 0, I = 1,..., N. This characteristic structure is the same for all first-order systems (d) and is explicitly dependent upon constants of motion of the system.
