1.	In figures (a), (b) and (c) shown, the objects A, B and C are of same mass. String, spring and pulley are massless. C strikes B with velocity u in each case and sticks it. The ratio of velocity of B in case (a) to (b) to (c) is
Answer» (a) `1:1:1` (B) `3:3:2` (C) `3:2:2:` (d) `1:2:3` SOLUTION :`v_a=v_b=v/2` `v_c=v/3` `:. v_a:v_b:v_c=3:3:2`
