R1 R2 FIGURE 8-1 A solid cylinder of mass 10 kg is pivoted about a frictionless axis thought the center O. A rope wrapped around the outer radius R1 = 1.0 m, exerts a force F1 = 6.0 N to the right. A second rope wrapped around another section of radius R2 = 0.50 m exerts a force F2 - 6.0 N downward. How many radians does the cylinder rotate through in the first 5.0 seconds, if it starts from rest? O 5.0 rad 10 rad O 7.5 rad O 13 rad
