When ex-ante Aggregate Supply (AS) is less than ex-ante Aggregate Demand (AD), it creates an inflationary gap in the economy, resulting in:
- Increase in Output: Firms increase production to meet the higher demand for goods and services.
- Increase in Income: Higher production leads to increased payments to factors of production, resulting in higher income levels.
- Increase in Employment: Firms hire more workers to increase production, thereby creating additional employment opportunities.

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?
