B. Determination of ux (accelerated motion) 1. Open the Level Surface Kinetic Friction Simulation https://www.geogebra.org/m/mgdhbb4k 2. Choose your bottom material wood . 3. Select a mass mh. 4. Click the 'Start Simulation' button. 5. Look at the graph. The slope of the best fit line will be the acceleration. You want your slope to be around +0.5 to +0.6 m/s^2. Repeat steps 3 and 4 until that happens, and then record me and the acceleration, a, in Table 3. A sample screenshot is given below. GeoGebro Colin Accelerated Kinetic Friction Lab - 90.1 6. Hit the bottom button (says "my = 120. g" by default) to add or remove 120. g to the block, reset the simulation, and repeat steps 3 - 5. Change the bottom material to felt and repeat steps 3 - 6. Take a screenshot of the simulation for any trial for felt. The web address, Date, and time of the device that you used should be visible in the screenshot. Inset here. Add more space if needed. Screenshot(2)T. Use your recorded values to calculate your coefcients of kinetic friction, Ja]; (use equation 6. Replace ml with 12a.J or tab + m\". depending on the values and u With nib) 3. Calculate the percent difference between the weighted and unweighted cases. TABLE 3. Wood on Aluminum my =12l]. g new =12D. g "/di': Show your pk calculations (equation with numbers plugged-in). TABLE 4. Felt on Aluminum my, = 121:}. g In... =12l]. g %di'= Show your pk calculations (equation with numbers plugged-in)
