A system is shown in the figure. A man standing on the block is pulling the rope. Velocity of the point of string in contact with the hand of the man is \( 2 \mathrm{~m} / \mathrm{s} \) downwards. The velocity of the block will be: [Assume that the block does not rotate]
(a) \( 3 \mathrm{~m} / \mathrm{s} \)
(b) \( 2 \mathrm{~m} / \mathrm{s} \)
(c) \( 1 / 2 \mathrm{~m} / \mathrm{s} \)
(d) \( 1 \mathrm{~m} / \mathrm{s} \)
