The last stanza of the poem, "through the knocked-out clockwork, after the riot, a peace-march time bomb, or a precise act of nature in light of lightning," reflects the title of the poem, "Time and Time Again". It shows that after many quarrels, conflicts and communal disharmony, a peaceful time may arrive soon. But, as we say, "when winters come, can spring be far behind", which sometimes means we can experience a good time once bad times have passed and gone away.

A ladder of fixed length \( h \) is to be placed along the wall such that it is free to move along the height of the wall.
Based upon the above information, answer the following questions:
(iii) (b) If the foot of the ladder, whose length is 5 m, is being pulled towards the wall such that the rate of decrease of distance \( y \) is \( 2 \, \text{m/s} \), then at what rate is the height on the wall \( x \) increasing when the foot of the ladder is 3 m away from the wall?
