An accelerometer (a device to measure acceleration) can be as simple as a small pendulum. Suppose you are flying a small plane in a straight horizontal line and your accelerometer hangs 10 behind the vertical. What is your acceleration? (Use the numbers given in the question)

You mean 10 degrees? If so, your acceleration is sin(10)*9.8 = 1.7 m/s^2.

Acceleration is zero if you're traveling at a consistent 10 behind the vertical.

I'm pretty sure I'm right. Acceleration is about the change in speed or direction. The situation described above is stable: Hanging 10 behind the vertical and flying is a straight line.

Or maybe I'm wrong.. who cares

F=ma is the horizontal force due to the plane's acceleration and L=mg is the vertical load due to the mass. The line made by the pendulum denotes the resultant direction of the two forces thus,
tan10=F/L=ma/mg=a/g
a=g*tan10=9.81*tan10=1.73 m/s^2

Runintlkt, thats not right. If there were no acceleration, the pendulum would be vertical.

10 is 10 degrees then
m.a force due to acceleration of the plane
m.g force due to hearth gravity

m.a/m.g=Tg(10)

a=Tg(10)*m*g/m
a=Tg(10)*g
