[SOLVED] In a popular amusement-park ride, a cylinder of radius 2.00 m is set in rota 1. The problem statement, all variables and given/known data In a popular amusement-park ride, a cylinder of radius 2.00 m is set in rotation at an angular speed of 6.00 rad/s, as shown in Figure 7-20 (http://www.webassign.net/sfhs99/7-20.gif). 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? 2. Relevant equations mu = g/omega^2*R 3. The attempt at a solution mu= 9.8/36*2 = .54 but it says im incorrect..
