A Ferris wheel with a radius of 9.5 m rotates at a constant rate, completing one revolution every 23 s. If this Ferris wheel begin to decelerate at the rate of 0.22 rad/s2 when the passenger is at the top of the wheel. Find the magnitude and the direction of the passengerâs acceleration at that instant it starts decelerating.
