Unformatted text preview: ground is not moving. Rolling After one rotation, the wheel has covered a distance equal to its circumference So 2 π R v = T = 2 π ω v =ω R Example A cylinder rolls without slipping down an incline that makes an angle of 30 degrees with the horizontal. What is the acceleration of the cylinder?...

### 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.
