Explanation:

In Washington Irving's short story "The Adventure of the Mysterious Stranger", the unnamed narrator talks of how he had befriended a stranger who "would turn his head slowly round, give a glance over his shoulder, and then withdraw it with a sudden je rk, as if something painful had met his eye". This newfound mystery sparked an interest in him to know more about the stranger.

After he had befriended him and they usually hung out, he still saw that the stranger appeared to be the same. He's sometimes see him with "his face on the sofa: his hands clinched in his fine hair, and his whole countenance bearing traces of the convulsions of his mind". This used to happen even after a whole scene of revelry and other activities that may be deemed enjoyment. But to the stranger, back in his room, he became the same man- lonely and seemingly in pain. The narration in this given passage suggests the mounting helplessness and pain and agony that the stranger must be going through.

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.
