SUMMARY
The discussion centers on a physics problem involving a bus accelerating from an initial speed of 30.0 km/h at a constant rate of 3.5 m/s² over a duration of 6.8 seconds. The book states the final velocity as 120 km/h, while the user calculates it to be approximately 115.67 km/h. The discrepancy arises from the consideration of significant figures, where the book rounds the answer to two significant figures. The user confirms their calculations are correct, acknowledging the importance of significant figures in reporting results.
