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 3.2 m/s, and an 83 kg person feels a 525 N force pressing against his back. What is the radius of the chamber?
Fc = mv^2/r
Fc is given and v is given. Substitute and solve for r
