SUMMARY
The minimum angular velocity required to prevent a person from slipping down a vertical cylinder with a radius of 6.56 m and a coefficient of static friction of 0.61 is determined by analyzing the forces acting on the person. The centripetal force necessary for circular motion is provided by the normal force exerted by the wall, which must counteract the gravitational force acting on the person. The relationship between these forces leads to the calculation of the angular velocity needed to maintain the person against the wall without slipping.
