Two bars of masses `m_1` and `m_2` connected by a weightless spring of stiffness `k`, rest on a smooth horizontal plane. Bar `2` is shifted by a small distance `x_0` to the left and released. The veloicyt of the centre of mass of the system when bar 1 breaks off the wall is

A

`(xsqrt(m_(2)k))/(m_(1)+m_(2))`

B

`xsqrt(K/(m_(1)+m_(2))`

C

`(xsqrt(m_(1)k))/(m_(1)+m_(2))`

D

`(sqrt(m_(1)k))/(m_(1)+m_(2))`
