On a friction surface a block a mass `M` moving at speed `v` collides elastic with another block of same mass `M` which is initially at rest . After collision the first block moves at an angle `theta` to its initial direction and has a speed `(v)/(3)`. The second block's speed after the collision is

A

`(sqrt(3))/(2)v`

B

`(2sqrt(2))/(3)v`

C

`(3)/(4)v`

D

`(3)/(sqrt(2))v`
