Find Static and Kinetic Friction Coefficients between a friction cart and friction apparatus under a horizontal condition. (From Lab Manual)1. Log in to the computer using your UCID and password 2. Connect the USB cable of the 850 Universal Interface to a USB port on the computer 3. Connect the AC adapter power cord to an electrical outlet under the lab table 4. Press the power push button on the left corner of the interface. The green LED indicator belowthe power push button should light up 5. Open Lab 106 Friction file in Physics 102A Lab Experiments” folder on Desktop. You will see“Measurement” “Analysis 1” and “Analysis 2” pages on the screen 6. Measure the mass of the friction tray. Record these values 7. Plug the force sensor to “PASPort 1” input and press “Zero” button on the sensor with no forceapplied. 8. Put a mass in the Friction Tray. Connect the friction tray to the Force Sensor using the string 9. Go to the page of “Measurement” and click “RECORD” button on the bottom of the screen” 10. Place the Friction Tray on a lab table. With the force sensor tied to the tray, slowly pull the Friction Tray horizontally, from rest, across the lab table until it reaches a constant velocity.
