A small smooth disc of mass `m` and radius moving with an initial velocity `'v'` along the positive `x-` axis collided with a big disc of mass `2m` and radius `2r` which was initially at rest with its centre at origin as shown in figure.

If the coefficient of restitution is `0` then velocity of larger disc after collision is

`8/27vhati-(2sqrt(2))/27vhatj`

`8/27vhati-(sqrt(2))/27vhatj`

`v/3hati`

`(2sqrt(2))/27vhati-8/27vhatj`
