PROCEDURE Part I 1. Connect the Motion Detector to the digital (DIG) port of the interface. Set the ,x Motion Detector sensitivity switch to Track. a 2. Conrm that your Dynamics Track, Adjustable End Stop, and Motion Detector Bracket are assembled as shown in Figure 1. Adjust the head of the Motion Detector so that it is pointing straight down the track, or angled up just a little. 3. Open the le \"03 Cart on a Ramp\" from the Physics with Vernier folder. 4. Place the cart on the track near the end stop. Face the plunger away from the Motion Detector. Click ' \""9\" to begin data collection1 . You will notice a clicking sound from the Motion Detector. Wait about a second, then briey push the cart up the incline, letting it roll freely up nearly to the top, and then back down. Catch the cart as it nears the end stop. 5. Examine the position vs. time graph. Repeat Step 4 if your position vs. time graph does not ShOW an area of smoothly changing position. Check with your instructor if you are not sure whether you need to repeat data collection. 6. Answer the Analysis questions for Part I before proceeding to Part II. Part II 7. Your cart can bounce against the end stop with its plunger. Practice starting the cart so it bounces at least twice during data collection. 8. Collect another set of Motion Detector data showing two or more bounces. 9. Proceed to the Analysis questions for Part
