In a popular amusement-park ride, a cylinder of radius 4.00 m is set in rotation at an angular speed of 4.00 rad/s, as shown in Figure 7-20. The floor then drops away, leaving the riders suspended against the wall in a vertical position. What minimum coefficient of friction between a rider's clothing and the wall of the cylinder is needed to keep the rider from slipping? (Hint: Recall that Fs = µsFn, where the normal force is the force that maintains circular motion.)
