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.

During the apollo moon missions, astronauts were concerned about the effects of newton's third law of motion when: o a. they ejected waste water, because they were concerned that it would push them off course. o b. they reentered earth's atmosphere, because they were carrying heavy moon rocks. o c. they took off from earth, because a large force was required to generate large acceleration. o d. they detected incoming space debris, because the inertia of the debris could damage their ship.
