Randall D. Knight β Impulse and Momentum: Problem 17
Three identical train cars, coupled together, are rolling east at speed \( v_0 \). A fourth car traveling east at \( 2v_0 \) catches up with the three and couples to make a four-car train. A moment later, the train cars hit a fifth car that was at rest on the tracks, and it couples to make a five-car train. What is the speed of the five-car train?
