According to Bergman, one cannot put a novel into a film entirely. It becomes a complete injustice to the book because it triggers the intellectual faculty, whereas the movie triggers emotions directly.
However, according to Umberto Eco, the film takes over the popularity of a novel. It is only when the movie is made out of a book that it reaches the epitome of its popularity. So, the film indirectly helps the novel. Thus, Bergan believes that the individual effect of each of these two art forms on the audience is different from each other.

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?
