Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A uniform 4-kg cylinder A, of radius r= 150 mm, has an angular velocity wo = 52 rad/s when it is brought into contact with an identical cylinder B, which is at rest. The coefficient of kinetic friction at the contact point Dis uk. After a period of slipping, the cylinders attain constant angular velocities of equal magnitude and opposite direction at the same time.
