Two identical 1350-kg automobiles A and B are at rest with their brakes released when B is struck by a 5600-kg truck C which is moving to the left at 8 km/h. A second collision then occurs when B strikes A. Assuming the first collision is perfectly plastic and the second collision is perfectly elastic, determine the velocities of the three vehicles just after the second collision. The velocity of car A is VA = km/hr + km/hr +. The velocity of car B is vg= The velocity of truck C is vc= km/hr ←.
