    Two equal masses \[{{m}_{1}}\] and \[{{m}_{2}}\] moving along the same straight line with velocities \[+\,3\,m/s\] and \[-\,5\,m/s\] respectively, collide elastically. Their velocities after the collision will be respectively

    A) \[-\,3\,m/s\] & \[+\,5\,m/s\]         

    B) \[+\,4\,m/s\] for both

    C) \[-\,4\,m/s\]& \[+\,4\,m/s\]          

    D) \[-\,5\,m/s\] &\[+\,3\,m/s\]

    Correct Answer: D

    Solution :

    [d] In elastic collision, the velocities get inter changed if the colliding objects have equal masses.
