The blocks in Fig. 6-23 slide without friction. What is the ve- locity v of the 1.6-kg block after the collision? 5.5 m/s 2.5 m/s 1.6 kg 2.4 kg Before collision S/ 4.9 m/s 1.6 kg 2.4 kg After collision A barge with mass 1.50 X 105 kg is proceeding downriver at 6.20 m/s in heavy fog when it collides broadside with a barge heading directly across the river; see Fig. 6-25. The second barge has mass 2.78 X 105 kg and was moving at 4.30 m/s. Immediately after impact, the second barge finds its course deflected by 18.0 in the downriver direction and its speed in- creased to 5.10 m/s. The river current was practially zero at the time of the accident. What is the speed and direction of motion of the first barge immediately after the collision? 180
