Data Analysis for DataStudio:

    1. Plug the first Xplorer into the USB port on the computer. A dialog box will appear indicating that data is available for download. Click the Retrieve Now button and the data will be brought into DataStudio.


    2. Repeat Step 1 for the second Xplorer. Since the Xplorers have an onboard clock that was synchronized prior to the experiment, the data will be merged such that the data from the separate Xplorers will be aligned on the time axis.
    3. Look at the velocity-time data and try to find a common velocity for each of the four data runs. You will need to record the corresponding centripetal acceleration for this common velocity.



    4. Once you have decided on a common velocity at which to record the centripetal acceleration, use the Data button to turn off all data runs except Run #1.


    5. Turn the Smart Cursor on for both graphs and drag the velocity-time Smart Cursor to the common velocity that you decided on in step 3.



    6. Record the corresponding centripetal acceleration in the table.
    7. Repeat steps 4-6 for the other three data runs that correspond to the different radii.
