In an old-fashioned amusement park ride, passengers stand inside a \( 3.0 \)-m-tall, \( 5.0 \)-mdiameter hollow steel cylinder with their backs What is the minimum rotational frequency, in rpm, for which the ride is safe? against the wall. The cylinder begins to rotate about a vertical axis. Then the floor on which the passengers are standing suddenly drops away! If all goes well, the passengers will "stick" to the wall and not slide. Clothing has a static coefficient of Express your answer in revolutions per minute. friction against steel in the range \( 0.60 \) to \( 1.0 \) and a kinetic coeficient in the range \( 0.40 \) to \( 0.70 \). \[ f= \] rpm
