1. The problem statement, all variables and given/known data You are designing a new amusement park ride called Barrel o’ Fun. The idea is that people will stand inside a barrel with their backs against the wall. It takes 1.5 seconds for the barrel to complete one revolution. The diameter of the barrel is 15 meters. What coefficient of friction will be necessary for the people to stick to the wall so that when the barrel is spinning the floor can drop away? 2. Relevant equations Force of Static Friction = Coefficient of Static Friction × Normal Force = mv^2/r Fs = μs×N = mv^2/r μs = mv^2/rN μs = v^2/rg μs = 4∏^2r^2/rgt^2 3. The attempt at a solution μs = 4∏^2r^2/rgt^2 μs = 13.4143 This does not seem right. I would appreciate your help.
