At a amusement park there are 180kg bumper cars A, B and C that have riders, as shown, with masses 40 kg, 60kg, and 30 kg respectively. Car A is moving to the right with a velocity Va=2m/s and car C has a velocity Vc=1.5 m/s to the left, but car B is initially at rest. If the coefficient of restitution between each car is.85, determine the final velocity of each car, after ll impacts, assuming cars A and C hit car B at the same time.
