4. Click on the Masses button and choose a mass for the hover puck in the range of 800 g - 1,500 g. Record the hover puck's mass. DO NOT change the mass of the hover puck (on the frictionless table) for this section of the lab. 5. For the first trial, change the hanging mass to 10 g and record in the Data Table. Click the Return button. 6. Click on the Start button. The system will respond and the Position (cm) and Elapsed Time (ms) chart under the table will automatically fill-in. NOTE: ms stands for milliseconds. Record the time in seconds for 100 cm in the Data Table. 7. Repeat three more times for a total of four trials per each M, value. Calculate the average time from your four trial times. 8. Increase the hanging mass, and repeat steps 6 and 7
