A Ferris wheel with a radius of 9.3 m rotates at a constant rate, completing one revolution every 36 s . Suppose the Ferris wheel begins to decelerate at the rate of 0.18 rad/s^2 when the passenger is at the top of the wheel. Find the magnitude of the passenger's acceleration at that time.
Express your answer using two significant figures.
a =
Find the direction of the passenger's acceleration at that time.
Express your answer using one decimal place.
