An accelerometer—a device to measure acceleration—can be as simple as a small pendulum hanging in an airplane cockpit. An essentially similar accelerometer is found in the inner ear of vertebrates. Suppose you are flying a small plane in a straight, horizontal line and your accelerometer hangs at a constant angle of 12° behind the vertical, as shown in the figure. What is your acceleration?
