The blocks \( A \) and \( B \) shown in figure have masses \( M_{A}=5 \mathrm{~kg} \) and \( M_{B}=4 \mathrm{~kg} \). The system is released from rest. The speed of \( B \) after \( A \) has travelled ? distance \( 1 \mathrm{~m} \) along the inclink i
(1) \( \frac{\sqrt{3}}{2} \sqrt{g} \)
(2) \( \frac{\sqrt{3}}{4} \sqrt{g} \)
(3) \( \frac{\sqrt{g}}{2 \sqrt{3}} \)
(4) \( \frac{\sqrt{g}}{2} \)
