The 300 kg and 400 kg mine cars are rolling in opposite directions along the horizontal track with the respective speeds of 0.6 and 0.3 m/s. Upon impact the cars become coupled together. Just prior to impact, a 100 kg boulder leaves the delivery chute with a velocity of 1.2 m/s in the direction shown and lands in the 300 kg car. Calculate the velocity v of the system after the boulder has come to rest relative to the car. Would the velocity be the same if the cars were coupled before the boulder dropped?
