Two identical balls A and B having velocities of 0.5 m/s and -0.3 m/s

1.	Two identical balls A and B having velocities of 0.5 m/s and -0.3 m/s respectively collide elastically in one dimension. The velocities of B and A after the collision repsectively will be ……….
Answer» `-0.3 m//s , 0.5 m//s ` `0.3 m//s ,0.5 m//s ` `-0.5 m//s ,0.3 m//s ` `0.5 m//s , -0.3 m//s ` SOLUTION :SINCE both balls are IDENTICAL and collision is elastic so VELOCITY will interchange . So `v_(B) = 0.5 , v_(A) = - 0.3 `
