A body is moving with a velocity \( v \), breaks up into two equal parts. One of the part retraces back with velocity \( v \). Then the velocity of the other part is
[DCE 2004]
(a) \( v \) in forward direction
(b) \( 3 v \) in forward direction
(c) \( v \) in backward direction
(d) \( 3 v \) in backward direction
