During Montag’s escape, what new “game” do the police invent? What similarities does this game have to entertain in our society?

The new game suggested by the police is for everyone to look out the window, or open their doors so that the fugitive doesn't escape.

Explanation:

What the police do when Montag escapes and is a fugitive is to ask all the inhabitants, as if it were a kind of game, to open the front or rear doors of the houses or to look out the windows.

In this way, the only one running through the city and escaping would be Montag and so they could get him. Still, Montag managed to get to the river in time before anyone could see it.

This "game" resembles a treasure hunt or any type of hunt today.

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.
