## Homework Statement

An accelerometer—a device to measure acceleration—can be as simple as a small pendulum hanging in the cockpit. Suppose you are flying a small plane in a straight, horizontal line and your accelerometer hangs 12° behind the vertical, as shown in the figure. What is the magnitude of your acceleration at that time?

## Homework Equations

Thought SumF = ma, but I have no idea.

## The Attempt at a Solution

Ok so I did the FBD for this, but I really have no idea how to go about this. I've tried angular acceleration formulas, etc, but the answer has been wrong. I've been working on Physics HW now for 4 hours and this is the final one, but I really have no idea how to go about this.
