Three blocks are initially placed as shown in the figure. Block `A` has mass `m` and initial velocity `v` to the right. Block `B` with mass `m` and block `C` with mass `4m` are both initially at rest. Neglect friction. All collisions are elastic. The final velocity of blocks `A` is

Three blocks A, B and C each of mass m are placed on a surface as shown in the figure. Blocks B and C are initialyy at rest. Block A is moving to the right with speed v. It collides with block B and stricks to it. The A-B combination collides elastically with block C. Which of the following statement is (are) true about the velocity, of block B and C.
