Explanation & Answer
Using the Pythagorean Theorem, we find:
d2 + d2 = (4r)2
2d2 = 16r2
r2 = d2 ÷ 8
r = d ÷ 2(√2)
r = 1.3748 x 10¯8 cm///////////////////////

Cuyamaca Gollege Kinetic and Static Friction Coefficients Lab Report
There are 2 parts to this lab, static friction (Links to an external site.) and kinetic friction (Links to an external site.).For static friction find the largest angle before slipping. There are buttons for large and small changes to the angle. There is also a button to stop the mass (remember, once moving, static friction becomes kinetic). Pressing the "Check" button will tell you if you have the correct angle or not - once you find it, the controls are replaced by a data download link. Repeat this for each of the 4 orientations.For kinetic friction, you will add mass to the cart via a menu. You need to choose a single value for each of the 6 runs. It needs to be enough to accelerate with Cart+250g. Once you find a good number, start the simulation and download the data - to be analyzed on Logger Pro as we did last time.Go tohttps://www.vernier.com/downloads/logger-pro-demo/ (Links to an external site.)•••The loggerpro demo is being updated... in the meantime:•••MacOSX: http://www.vernier.com/d/mykwv (Links to an external site.)•••Windows7,8,10: http://www.vernier.com/d/lxaih (Links to an external site.)and download logger pro for PC or Mac. Install the program.Run the Logger Pro application. Under the FILE menu, go to the "Import From..." menu item. Choose "Text File..."Then either go to the Analyze menu and selected Curve Fit, or find the Curve Fit button (looks like a U on top of an M).On the curve fit page, choose "Quadratic" and click on "Try Fit", then press OK. Record the value of A ± σA and repeat for the 9 combinations of hanging mass and cart mass.Video Lecture: Watch the discussion (Links to an external site.)DATA ENTRY WEBSITE: https://stemplosion.com/2019_labs.asp?c=0321
