In a popular amusement park ride, a rotating cylinder of radius3.00 m is set in rotation at an angular speed of 6.00 rad/s, as inFigure P7.51. The floor then drops away, leaving the riderssuspended against the wall in a vertical position. What minimumcoefficient of friction between a rider's clothing and the wall isneeded to keep the rider from slipping? (Hint: Recall that themagnitude of the maximum force of static friction is equal to µn,where n is the normal force - in this case, the force causing thecentripetal acceleration.)
