A particle of mass $m$ moving with velocity $v$ collides with a stationary particle of mass $2 m$ . After collision, they stick together and continue to move together with velocity

Options:

Answer:

Solution:

Applying conservation of linear momentum
$\Rightarrow P_{i} = P_{f} (∵ P = mv)$
$m v_{1} + 2 m v_{2} = (m + 2 m) v^{'}$
$m v^{1} + 2 m \times 0 = (3 m) v^{'}$
$\Rightarrow mv = 3 mv^{'} \Rightarrow v^{'} = \frac{v}{3}$
