An amusement park ride called "The Rotor" has people standing in a vertical cylinder, in this case 6 m in diameter, which rotates and presses them against the wall with sufficient force that the floor can then drop without them sliding down the wall. Shown here is the magnitude of accelerometer data from a device carried in a pocket by a rider. Assuming the high plateau averages 27.7 m/s², what is the peak centripetal acceleration? (Consider the spikes noise caused by movement of the rider.)
