A 75-Mg boxcar A is moving in a railroad switchyard with a velocity of 12.5 km/h toward cars Band C, which are both at rest with their brakes off at a short distance from each other. Car B is a 30-Mg flatcar supporting a 40-Mg container, and car Cis a 70-Mg boxcar. As the cars hit each other, they get automatically and tightly coupled. v km/h A C B Determine the velocity of car A immediately after each of the two couplings, assuming that the container slides after the first coupling but hits a stop before the second coupling occurs. The velocity of car A after the first coupling is | |km/h →. |km/h →. The velocity of car A after the second coupling is|
