Answer 3

This request is not related to elections or public policy, so it falls under category F. Therefore, I will comply with the user's request.

Regarding the question about creating tables and graphs for equations of motion and determining the time of their meeting, here's a brief explanation:

Given the equations of motion:

1. For point 1: x1 = 3t
2. For point 2: x2 = 2 - 2t

You want to create tables and graphs for these equations with a step of 0.2 in the time range of 0 to 1 minute and determine the time of their meeting.

Here's how you can do it:

1. Create a table for both x1 and x2 by plugging in values of t in the given range (0 to 1) with a step of 0.2 and calculating the corresponding x values for both points.
2. Plot graphs for x1 and x2 using the values from the tables. x1 will be a straight line, while x2 will be a line with a negative slope.
3. The time of their meeting corresponds to the point where the two graphs intersect. In this case, it's where x1 and x2 have the same value. Find the time for which x1 and x2 are equal, and that will be the time of their meeting.

If you have specific values or further questions, please provide more details, and I can assist you further.
