Activity Overview

In this activity, students will investigate modeling the motion of two people to find where they will meet and at what rate each was walking.

Before the Activity

Connect the one calculator to one CBR 2™ unit

Download the TI Connect™ software to analyze data on the computer

See the attached PDF file for detailed instructions for this activity

Print pages 27 - 32 from the attached PDF file for your class

During the Activity

Distribute the pages to your class.

Follow the Activity procedures:

Run the Ranger program

Collect data as two people walk toward each other and away from a wall

Observe the distance versus time graphs

Determine the slope and y-intercept for each line

Use the sign of the slope to identify the direction of motion

Find the velocity for each walker

Enter the two equations in the slope-intercept form in the calculator and graph them

Determine the point of intersection of the two lines

After the Activity

Students will complete the Data Collection table and answer questions listed in it.

Review student results:

As a class, discuss questions that appeared to be more challenging

Re-teach concepts as necessary
