Gary rides on a ferris wheel that takes 10.0 s to go once around; the radius of the wheel is 12.0 m.
(a) what is Gary's acceleration (magnitude and direction) when he reaches the lowest point of the ride?
(b) what is his acceleration (magnitude and direction) when he reaches the highest point of the ride?
(c) When the conductor applies the break, Gary's speed decreases at a constant rate of 4.0 m/s^2; what is the magnitude of Gary's acceleraion after the break has been acting for 1.0 sec?
