A Ferris wheel with a radius of 9.1 m rotates at a constant rate, completing one revolution every 38 s.
Suppose the Ferris wheel begins to decelerate at the rate of 0.21 rad/s2 when the passengers at the top of the wheel.
A) Find the magnitude of the passenger's acceleration at that time.
B) Find the direction of the passenger's acceleration at that time, in degrees below the direction of motion.
