## Homework Statement

A ferris wheel with radius 14.0m is turning about a horizontal axis through its center. The linear speed of a passenger on the rim is constand and equal to 7.69m/s. What is the magnitude of the passenger's acceleration as she passes through the lowest point in her circular motion?

## Homework Equations

## The Attempt at a Solution

Because the speed is constant I thought that the magnitude of the acceleration would be zero and only the direction of the acceleration would have a value, but zero isn't the right answer so there's a concept to answering this question that I'm completely missing and I have no idea how to go about finding it. Does the fact that the person is at the lowest point make a difference? All of this is very new to me and I'm just very confused.
