हिन्दीTwo 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:
Correct answer · Option 4
2 : 1
Explanation
By conservation of linear momentum: \( m v_1 + m(0) = (m + m) v_2 \implies m v_1 = 2m v_2 \implies \frac{v_1}{v_2} = \frac{2}{1} = 2 : 1 \).
