A space craft of mass $'M' $ and moving with velocity $ 'v' $ suddenly breaks in two pieces of same mass $m$. After the explosion one of the mass $ 'm'$ becomes stationary. What is the velocity of the other part of craft

$\frac{{Mv}}{{M - m}}$
$v$
$\frac{{Mv}}{m+M}$
$\frac{{M - m}}{m}v$

By the principle of conservation of linear momentum,
$Mv = m{v_1} + m{v_2}$==>$Mv = 0 + (M - m){v_2}$==>${v_2} = \frac{{Mv}}{{M - m}}$
