Question

According to momentum conservation.

$mv = m / 3$ $ 	imes \,0 + \frac{{2m}}{3}\,v'$

$mv = \frac{{2m}}{3}\,v'\,\,$

${v' = \frac{3}

$\frac{3}{2}\,v$

Vedclass · Answer

According to momentum conservation.

$mv = m / 3$ $ 	imes \,0 + \frac{{2m}}{3}\,v'$

$mv = \frac{{2m}}{3}\,v'\,\,$

${v' = \frac{3}{2}v}$

A shell of mass $m$ moving with velocity $v$ suddenly breaks into $2$ pieces. The part having mass $m/3$ remains stationary. The velocity of other part will be
