1. Open your spreadsheet from the Run Lab.
2. Calculate the speed of each runner in the last interval of the run. From 35-40 yards.
3. Convert yards/second to meters per second using this converter.
3. Find the acceleration of each runner by using zero as the starting speed and time, and the final velocity you calculated in #2. Use the total time for the run for the time in your acceleration calculation.
4. Create a text document and write a lab report.
5. Save it as your full name and “Run Lab” and put it in SLAMA>Class folder>Physics5,6,7>Run Lab

1. Velocity and Acceleration Notes (page 12) with Example Problems.
2. Acceleration Problems. Do these problems.
3. Find the acceleration of each of the four runners from yesterday. Use zero velocity at zero time for your first velocity. Use their final velocity as your second point.

Running Lab
Today we go to the track and run laps. Just kidding. We will go to the track and measure the acceleration of 4 runners starting from a standstill up to running to full speed.
Measure the position vs. time every 5 yards for four people running a 40 yd. dash.
When we return from the track, share numbers, enter the values into a spreadsheet, and graph each runner’s position vs. time. we’ll analyze the data to find acceleration tomorrow.
Homework: Read 13-16 and answer Review Questions 1-14 on page 25.

1. Review for Quiz
2. Instructions for finish of Bancroft Car Lab
2. Take Quiz
3. Finish the Bancroft Car Lab:
1. Double-Click on the graph and go to Insert >Trend Line. Click the box that says LINEAR and then Click the box that shows the equation. The number in front of the x in the equation is the slope of the line. This is the speed of the car in m/s.
2. Now go to File > New > Text Document and create a text document.
3. Create a document like the following:
Your Name
Title
Introduction/Purpose
What did you do, how did you do it, and why did you do it?
Graphs
Edit > Copy your graphs from the spredsheet and Edit > Paste them into this section.
Results
what speeds did you find for each car? What were the speeds in Mi/hr? Was anyone speeding?
4. Save it to your documents folder. Then go to the SLAMA hard drive > Class Folders > Physics5,6,or 7 > Car Lab and drop it in the folder.

1. Return and go over Quiz. Put into your notes as page 8.
2. Speed, distance, time notes [page 9]
3. Speed, distance, time problems. [page 10]
4. Adding a trend line to your graphs. If there is time, add a trend line to each of your graphs. Choose a linear fit and show the equation. The slope of the line is the speed of the car.
