Question

An amusement park ride called the Rotor consists of a room in the shape of a vertical cylinder (2.10 m in radius) which, once the riders are inside, begins to rotate, forcing them to the wall. When the room reaches a speed of one rotation every 1.36 s, the floor suddenly drops out. What is the minimum coefficient of static friction between riders and wall necessary to prevent them from sliding down the wall?
