Chapter 9, Problem 9.106(choose chapter or problem)
Two bumper cars in an amusement park ride collide elasticallyas one approaches the other directly from the rear (Fig. 9-56).Car A has a mass of 450 kg and car B 490 kg, owing to differencesin passenger mass. If car A approaches at 4.50 m/s andcar B is moving at 3.70 m/s, calculate (a) their velocitiesafter the collision,and (b) the change mA =in momentum of 450 kgeach.FIGURE 9-56 U) 106:(a) before collision,(b) after collision.
