1.	Two identical balls `A and B` having velocity 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 respectively will beA. `-0.3 ms^(-1) & 0.5ms^(-1)`B. `+0.5 ms^(-1) & +0.3ms^(-1)`C. `-0.4 ms^(-1) & 0.3ms^(-1)`D. `0.3 ms^(-1) & -0.4ms^(-1)`
Answer» Correct Answer - A In elastic collision of bodies of same mass, the velocities get mutually exchanged between them.
