Create 10 to 15 footnote annotations, or explain our notes, to define some of boyles more difficult language and show students how Boyle makes an argument through storytelling

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.

by explaining that it took the same total time to travel by plane as it did by train
