“This settlement was adopted unanimously by the commission. Gandhi explained that the amount of the refund was less important than the fact that the landlords had been obliged to surrender part of the money and, with it, part of their prestige. Therefore, as far as the peasants were concerned, the planters had behaved as lords above the law. Now the peasant saw that he had rights and defenders. He learned courage.”

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?
