Q3. As shown in the image below, the freight cars A and Bare approaching each other, and they have a mass of mA = 21 Mg and mg = 15 Mg, respectively. The directions of their initial velocities are shown in the image, and the speeds are VA,1 = 3.9 m/s and vB,1 = 3.0 m/s. After collision the cars rebound, such that B moves to the right with a speed of 1.7 m/s. If A and Bare in contact for 0.4 s, find the average impulsive force (in kN) which acts between them. Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point. VA,1 A VB,1 B
