PHYS 27/193: Homework 2

This assignment is due on Friday 25 by 10am.

The first assignment is to install jEdit on your computer. If it is already installed (if you are using the sunray for your scientific computer, then you are already done with this one).
You can email me with questions, but please try to install the program using the Installation Instructions which are lower down on the download page. If you have trouble, write down exactly what the error is so that I can help you.
Note that you may need both a Java Runtime Environment (JRE) as described above, in addition to jEdit's installer from the jEdit site. On the other hand the JRE may already be installed on your computer.
jEdit is installed correctly when the splash icon comes up as it's starting up (a box that says jEdit), and the editor window comes up after.

Create and save a file called "NAMEtext.txt" (where NAME is your last name) which has the lines:

       This is my first ASCII text file using __jEdit__ (substitute editor).
       Physics is the Mother of All Sciences.
       I'm really __enjoying__ (substitute adjective) PHYS 27/193.

This data shows the Total US population, breakdowns by Urban and Rural amounts and percentages of the total, and breakdowns by region and state.

Make a text file called "NameCaPop.dat" with the following data in columns, as shown below.

Year       Total US            Total California
1900       76,212,168          1,485,053
1910       92,228,496          2,377,549
1920      106,021,537          3,426,861
etc...

You are to gather population data by year for the Total US population and the total California population in 3 columns. We will use this data in a future assignment.

Visit the following weboage:
Vertical Visions
Using jEdit type the data into a text file called "NAMEfreefall.dat" in the following format:
```
Time     Speed     Distance
(sec)	 (mph)      (feet)
1        10.91       16
2        31.36       62
3        51.81      138
etc...
```
We will use this data in the next part of our course.
Upload these files into the Digital Dropbox on BB. Note that they need to have your last name (or some abreviation of it) in the filename so that I can credit you.
