Question: A tank car is stopped by two spring bumpers A and B, having a stiffness of K A = 15(10) lb/ft and k B =

A tank car is stopped by two spring bumpers A and B, having a stiffness of K_A = 15(10³) lb/ft and k_B = 20(10³) lb/ft, respectively. Bumper A is attached to the car, whereas bumper B is attached to the wall. If the car has a weight of 25(10³) lb and is freely coasting at 3 ft/s, determine the maximum deflection of each spring at the instant the bumpers stop the car. A B WW WAL KA KB AB MM
