But tomorrow i die, and today i would unburthren my soul. why does poe place this line near the beginning of the story

My guess would be to get the reader thinking hard. They would ask the question like yu just did, "Why did he just say that at the beginning." My guess would be so they look fo clues to tell what he means by saying this. This is not how we normally write, so we would have to pay attention and look for clues to interperet what he means.

Good luck,

The correct answer is, to foreshadow events to come and make the reader wonder what the narrator has done.

they would have to clean it very clean

the boy's acceleration toward the girl is 2.08 m/s^2.

explanation:

according the newton's third law, the force causing the girl accelerate towards the boy will be me with equal counter-force causing the boy to accelerate towards the girl. these forces will be of equal magnitude and allows us to determine the boy's acceleration:

the boy's acceleration toward the girl is 2.08 m/s^2.
