In the poem, the poet Milton feels that it is not necessary to put up a monument in stone for Shakespeare because he had already made a mark in the minds of his readers. Instead, he had built a memorial for himself through his works which he would remember for a lifetime. Readers received Shakespeare's words the way one would accept the terms from God. Therefore, his statements created an everlasting impression in his readers' thoughts, which is mightier than a monument.

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?
