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) $2:1$
Concept. Momentum conservation in a perfectly inelastic collision.
Step 1. Equation. $mv_1 = 2mv_2 \Rightarrow v_2 = \dfrac{v_1}{2}$.
Answer. $2 : 1$ (Option D).
