A7.0-Mg truck is resting on the deck of a barge which displaces 329 Mg and is at rest in still water. If the truck starts and drives toward the bow at a speed relative to the barge vrel = 7.1 km/h, calculate the speed v of the barge. The resistance to the motion of the barge through the water is negligible at low speeds. P'rel = 7.1 km/h 7.0 Mg 329 Mg- Answer: v = i km/h
