We have obtained maps of the large-scale outflow associated with the UC H II region G5.89-0.39 in CO and ¹³CO (J=3-2), SiO (J=8-7, J=5-4), SO₂ (J=13_2,12-13_1,13),¹³ and H¹³CO⁺(J=4-3). From these maps we have been able to determine the mass (3.3 M_☉), momentum (96 M_☉km/s), energy (3.5x10⁴⁶ ergs), mechanical luminosity (141 L_☉), and mass-loss rate (∼1x10^–3 M_☉/yr) in the large-scale outflow. The observationally derived parameters were used to guide three-dimensional magnetohydrodynamic models of the jet-entrained outflow. Through the combination of observations and simulations, we suggest that the large-scale outflow may be inclined by approximately 45° to the line of sight, and that the jet entraining the observed molecular outflow may have been active for as little as 1000 years, half the kinematic age of the outflow.
