In an old-fashioned amusement park ride, passengers stand inside a 3. 0-m-tall, 5. 0-m-diameter hollow steel cylinder with their backs 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 friction against steel in the range 0. 60 to 1. 0 and a kinetic coefficient in the range 0. 40 to 0. 70.
