What is the purpose of an introduction paragraph?

Explanation:

The introductory paragraph is the most important of any essay, introducing the topic and setting the tone for the rest of the essay.

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.

oooh~ i love the salem witch trials.

sadly though, i cannot you if you don't post the paragraph. i'm confused on what to write!

if you would kindly post the paragraph though, i'm more than happy to you.
