As part of a series of tests, a crash dummy is placed in a centrifuge (a spinning chamber that makes it possible to apply varying accelerations to an object). The centrifuge looks like a hollow cylinder that rotates about its center. The crash dummy is set on the inner surface of the cylinder at a radial distance from the center of 2.7 m. At the end of the test, once the rotating cylinder had slowed to a rotation period of 2 seconds, the crash dummy was observed to just begin sliding down the surface of the cylinder. What must the coefficient of static friction between the crash dummy and the cylinder surface be? The coefficient of friction is unitless. Enter its numerical value in the box.
