Question

Put on your track shoes, walking shoes, grab your skateboard or bike... it's time to race. Bring a friend too as it will help you complete the 40-yard dash lab...anyone have any examples of how they did this assignment for online Algebra1a class, unit 6.02?

Answer 1

What's the actual assignment?

Answer 2

You're allowed to make up your friend's results.

Answer 3

Measure a distance of 40 yards by using a tape measure if you have one long enough or measuring a one-yard pace and stepping off 40 paces.
Mark the beginning and ending distance with some tape, chalk or string...a driveway, parking lot, sidewalk, open field, yard or quiet street will work well.
If you are using a race car instead of racing yourself, shorten the distance to 40 feet.
If you are going to run, make sure your muscles are warmed up and loose before doing any sprinting. Also make sure you cool down and stretch when you're finished.
If you're using your bike, rollerblades or skateboard, don't forget to wear your helmet and watch out for any traffic!

3. On your mark... get set... GO:

Have your friend time you and race from start to finish a minimum of five times and no more than 10 times.
If you're doing this lab alone, you will need to hold the stop watch in your hand and start/stop accordingly.
After each trial, record your time on a piece of paper.

4. Make a scatter plot graph

Create your graph from one of the following programs: Microsoft Word, Excel, or PowerPoint. Click on this icon Microsoft Word and print directions for graphing with Microsoft Word program.

OR

You can use the Graphmatica program to create your graph. Go to the Materials section of the Course Information area now if you want to download and install the Graphmatica program to complete your graphing for this assignment.

If you are using Graphmatica to create your graphs, here are the directions for using the tool:
Click on View, Data Plot Editor.
In the table to the right, enter your times for the X values and your rates for the Y values.
Enter your time in seconds in the X column. You then have to calculate your rate using the D = R x T formula. If your time was 5.5 seconds, then the formula is: 40 = R x 5.5 or 5.5R = 40 and thus R = 40/5.5 or R = 7.27.
You will need to adjust the viewing window on your graph. To do this, select View, Grid Range. Set your viewing window to Left -1, Right 10, Bottom -1, Top 10. (The -1 means negative 1.)
Save your graph to a word document by clicking Edit – Copy Graphs BMP. You can select monochrome or color. You now have the image copied and can paste it into any word processing document. (Control-P)
In the word processing document, be sure to give your graph a title and label your x and y axes.
Save the document as an rtf. Remember where you saved the graph and the name. Do not put decimals in your file name. You will later need to insert/attach this graph into your lab report.

5. Create your lab report

You will need to answer the following questions in your lab report.

Is the graph linear?
Is the relationship direct or inverse?
What would be the rate of someone running the 40 yard dash in 4.5 seconds?
What measurement was the "constant of variation" (didn't change)?
At a rate of 9.30 yards per second, how long would it take someone to run 100 yards?

Answer 4

Just make up your friend's results.

Answer 5

Are these all different questions??
