Block of \( 3 \mathrm{~kg} \) is initially in equilibrium and is hanging by two identical springs A and \( \mathrm{B} \) as shown in figures. If spring \( \mathrm{A} \) is cut from lower point \( \mathrm{at} \mathrm{t}=0 \) then, find acceleration of block in \( \mathrm{ms}^{-2} \) at \( \mathrm{t}=0 \).
