Activity 3—A Speedy Slide Parabolic

You have been familiar with playgrounds and slides since you were a small child. The force of gravity pulls you down a slide. The force of friction slows you down. In the first part of this experiment, you will use a CBR 2™ motion detector to determine your speed or velocity going down a playground slide. In the second part, you will experiment with different ways to increase your speed going down the slide.

Objectives

In this experiment, you will:

0use a CBR 2™ motion detector to determine your speed going down a slide

0experiment with ways to increase your speed going down the slide

0explain your results

Data collection, Part 1, Sliding Speed

ÊConnect the CBR 2™ motion detector to the calculator using an appropriate cable (see below) and firmly press in the cable ends.

0 If TI-83 Plus, TI-89, TI-92 Plus, TI-89 Titanium, Voyage™ 200, use an I/O unit-to- unit cable

0 If TI-84 Plus, use a Standard-B to Mini-A USB cable (unit-to-CBR 2™)

ËOn the calculator, press Œand select EasyData to launch the EasyData App or press 2°and select RANGER if you are using a calculator that does not operate with EasyData.

Note: EasyData will launch automatically if the CBR 2™ motion detector is connected to a TI-84 Plus using a unit-to-CBR 2™ cable.

ÎTo set up the calculator for data collection:

a.Select Setup (press p) to open the Setup menu.

b.Press 2 to select 2: Time Graph to open the Time Graph Settings screen.
