A lift is moving upwards with a constant speed of \( 5 \mathrm{~m} / \mathrm{s} \). The speed of one of the pulleys is \( 5 \mathrm{~m} / \mathrm{s} \) as
\( \mathrm{P} \)
shown. Then the speed of second pulley is
W
(1) \( 5 \mathrm{~m} / \mathrm{s} \)
(2) Zero
(3) \( 7.5 \mathrm{~m} / \mathrm{s} \)
(4) \( 10 \mathrm{~m} / \mathrm{s} \)
