In the figure shown block \( \mathrm{B} \) moves down with a
P velocity \( 10 \mathrm{~m} / \mathrm{s} \). The velocity of \( \mathrm{A} \) in the position shown is
W
(1) \( 12.5 \mathrm{~m} / \mathrm{s} \)
(2) \( 25 \mathrm{~m} / \mathrm{s} \)
(3) \( 6.25 \mathrm{~m} / \mathrm{s} \)
(4) None of these
