Question: In an old-fashioned amusement park ride, passengers stand inside a3.0-m-tall, 5.0-m-diameter hollow steel cylinder with their backsagainst the wall. The cylinder begins to rotate about a verticalaxis. Then the floor on which the passengers are standing suddenlydrops away! If all goes well, the passengers will stick to the wall and not slide. Clothing has astatic coefficient of friction against steel in the range 0.60 to1.0 and a kinetic coefficient in the range 0.40 to 0.70.

A) What is the minimum rotational frequency, in rpm, for which theride is safe?
