At an amusement park there is a ride in which cylindrically shaped chambers spin around a central axis. People sit in seats facing the axis, their backs against the outer wall. At one instant the outer wall moves at a speed of 3.4 m/s, and an 83 kg person feels a 595 N force pressing against his back. What is the radius of the chamber?
