30 m/s. It is just the same as if the car was parked and was struck by the object at 30 m/s. The jeep's 120 m/s plus the object velocity at 80 m/s gives the object a total velocity of 200 m/s. This is all assuming everything is going in a straight line and that the object's velocity is relative to the jeep, or it would be roadkill pretty quickly as the jeep would hit it immediately after firing it.
