## STOP

#### Activity Overview

In this activity, students will work with speeds in meters per second, and stopping distances in meters. An interactive page will evaluate problems for the student, and a spreadsheet will also perform the same calculations. With a collection of data values, the scatter plot reveals a relationship and a shape to the students. Finally, students are asked to perform the calculations and solve a radical equation themselves.

#### Key Steps

• After an introduction/review of converting between miles per hour and meters per second, students will use an interactive page to calculate the speed of the car, given a stopping distance.

• Discuss the material from the activity pages and worksheet with students as needed.

• Encourage students to summarize what they have learned from completing the activity. If desired, discuss the extension with students.
