A particle of mass $m$ moving with velocity $v $ strikes a stationary particle of mass $2m$ and sticks to it. The speed of the system will be
$v/2$
$2v$
$v/3$
$3v$
A particle of mass $m$ moving with velocity $v $ strikes a stationary particle of mass $2m$ and sticks to it. The speed of the system will be
Initial momentum = $mv$
Final momentum = $3mV$
By the law of conservation of momentum $mv = 3mV$
$V = v/3$
