Two bodies A and B of same mass undergo completely inelastic one dimensional collision. The body A moves with velocity $v_1$ while body B is at rest before collision. The velocity of the system after collision is $v_2$. The ratio $v_1 : v_2$ is :
Answer: (D) $2:1$
Momentum conservation (the bodies stick together):
$$mv_1 = (m + m)v_2 \;\Rightarrow\; v_2 = \frac{v_1}{2}$$
$v_1 : v_2 = 2 : 1$.
