A Solid Cylinder of Mass 10 Kg and Radius 1

Multiple Choice

A solid cylinder of mass 10 kg and radius 1.0 m rotates about its own symmetry axis. A rope wrapped around it exerts a 5.0-N force tangent to the cylinder, causing the cylinder to rotate clockwise. A second rope wrapped around another section of the same cylinder exerts a 6.0-N force that is tangent to the cylinder, causing the cylinder to rotate counterclockwise. The magnitude of the cylinder's angular acceleration is

A) 0.20 rad/s².
B) 0.91 rad/s².
C) 1.1 rad/s².
D) 10 rad/s².
E) 11 rad/s².
