Looking at your results for part I, do you obtain the same value for the coefficient of static friction for all of the different masses? Explain. - On the first part of the experiment, the coefficient of the static friction for all the different masses were the same for the same sled surface although different surfaces of the three sleds have different coefficient of static friction. The sled with wood surface has the highest coefficient of static friction which is 0.5 despite the different masses, the sled with clear plastic surface has lowest coefficient of static friction 0.1, and the sled with felt surface has 0.2 coefficient of static friction even though the masses were changing.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
