Q.
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;
A) 4 : 1
B) 1 : 4
C) 1 : 2
D) 2 : 1
Explanation
[Solution by Claude - not from source] $mv_1=2mv_2\Rightarrow v_1:v_2=2:1$. Answer (4).
