I really need help with this problem. I have one more attempt. Thank you

[0/1 Points] DETAILS PREVIOUS ANSWERS OSUNIPHYS1 6.3.WA.058. MY NOTES PRACTICE ANOTHER Consider an amusement park ride in which participants are rotated about a vertical axis in a cylinder with vertical walls. Once the angular velocity reaches its full value, the floor drops away and friction between the walls and the riders prevents them from sliding down. How many revolutions does the cylinder make each second, given that the minimum coefficient of static friction that is needed to keep the riders from sliding down is 0.555 and the diameter of the cylinder is 13.5 m? 0.6 X Did you draw a free-body diagram and label all the forces acting on a rider? What force provides the centripetal force needed for the circular motion? rev/s Additional Materials Reading
