Q11. As shown in the image below, the freight cars A and B are approaching each other, and they have a mass of mà = 22 Mg and må 14 Mg, respectively. The directions of their initial velocities are shown in the image, and the speeds are VA,1 5.2 m/s and VB.1 = 7.6 m/s. If the coefficient of restitution between the bumpers is e = 0.2, determine the velocity of A after collision. Right is considered the positive direction and negative sign must be included if A moves to the left after the collision. Please pay attention: the numbers may change since they are randomized. Your answer must include 3 places after the decimal point, and proper Sl unit. Your Answer: VA,1 Answer units = VB.1 ****4|||||||| B =
