Q6. A lift descends at \( 3 \, \text{m/s} \) and decelerates at \( 2 \, \text{m/s}^2 \) to stop. If a ball is dropped \( 1 \, \text{s} \) after deceleration begins, how far does it fall relative to the ground in \( 2 \, \text{s} \)? (Take \( g = 10 \, \text{m/s}^2 \))
- A. 20 m
- B. 19.75 m
- C. 22 m
- D. 18 m
