A Ferris wheel with a radius of 9.0 m rotates at a constant
rate, completing one revolution every 36 s .
Suppose the Ferris wheel begins to decelerate at the rate of 0.20
rad/s2 when the passenger is at the top of the wheel.
a)Find the magnitude of the passenger's acceleration at that time.
i got 1.8 and that was correct.
b) Find the direction of the passenger's acceleration at that time.
Homework Answers
angular acceleration
ar = r (2 pi / T) ^2 = 9* ( 2* 3.14 / 36)^2
ar = 0.2739 m/s^2
tangential acceleration
at = 9 * 0.2 = 1.8 m/s^2
direction
x = arctan ( ar/at) = 8.652 deg

Comment before rate in case any doubt, will reply for sure.. goodluck

A Ferris wheel with radius 8.5 m initially rotates clockwise at a constant rate by completing 2.00 rev in 28.00 s. It then begins to decelerate at a rate of 0.50 rad/s2 with its only passenger at the top of the wheel. Find the direction of the total acceleration vector. Express your answer as a positive number with respect to the positive x-axis. Choose up and to the right as your positive direction.

The Cosmoclock 21 Ferris wheel in Yokohama City, Japan, has a diameter of 100 m. Its name comes from its 60 arms, each of which can function as a second hand (so that it makes one revolution every 60.0 s). Find the speed of the passengers when the Ferris wheel is rotating at this rate. A passenger weighs 877 N at the weight-guessing booth on the ground. What is his apparent weight at the lowest point on the Ferris wheel?...
