A force of P = 20 N is applied to the cable, which causes the reel to turn without slipping on the two rollers A and B of the dispenser. Determine the angular velocity of the reel after it has rotated two revolutions starting from rest. Neglect the mass of thecable. Each roller has a moment of inertia of IR = 0.09 kg-mz, having a radius of 0.1m. The moment of inertia of the reel about its center axis is IG=30.87 kg-mz. GIVEN: ’P: ZOM I 01444,,“ +vfa‘l 0-3/0 5M?)

### 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.
