Two toy cars hit each other and have a perfect bounce. The mass of the 1st car is 7kg and it is going 2 m/s before the collision and -6.33 m/s after the collision. The 2nd car (mass 5kg) starts by going -8 m/s before the bounce/crash. What is the velocity of the 2nd car after the bounce? (ignore friction/heat losses and round to the nearest 100th)
