- B
$v_1 -v_2$ in original direction
- C
$v_2 -2v_1$ in original direction
- D
$2v_2 -v_1$ in original direction

Four smooth steel balls of equal mass at rest are free to move along a straight line without friction. The first ball is given a velocity of $0.4 \,m/s$. It collides head on with the second elastically, the second one similarly with the third and so on. The velocity of the last ball is .......... $m/s$
