Velocity of a block B instantaneously after collision is 0, because C is at rest.
Now use the concept of reduced mass and take A and B as one system and apply work energy theorem ,energy wrt COM there is only KE and finally only potential at maximum compression relative velocity wrt COM is 0
1/2*reduced mass * Vrel= 1/2kx^2

reduced mass is 2m/3
V relative is v

After substituting
ans is 1
