Louie Lemon rides on a Ferris wheel that takes 8.0 s to go once around; the radius of the wheel is 10.0 m.
(a) What is Louie's acceleration (magnitude and direction) when he reaches the lowest point of the ride?
(b) What is Louie's acceleration (magnitude and direction) when he reaches the highest point of the ride?
(c) When the conductor applies the brake, Louie's speed decreases at a constant rate of 2.0 m/s2; what is the magnitude of Louie's acceleration after the brake has been acting for 2.0 seconds?
