Question

An accelerometer is a device that uses the extension of a spring to measure acceleration in terms of Earth's gravitational acceleration (g). What is the approximate acceleration if this accelerometer spring is extended just 0.43 centimeters?

a) 0.24 g
b) 0.80 g
c) 2.00 g
d) 2.40 g

Answer 1

First of all you should find equation of the line. you need slope of the line and take a point on the line, then by using

\[y-y _{0}=m(x-x _{0})\] you get equation of the line

Then you should put 0.43 into equation, after then you can find easily what the answer is.

Answer 2

how do you know which one is the y and the y0 though?

Answer 3

y0 is a point that is on the line and y is variable.

Answer 4

I still don't understand.

Answer 5

y0 can only be 2.10 or 0.53 but y can be any number which is on the line. For instance 1 or 1.0056 or 2.54 or 0.89.

Answer 6

Thanks.

Answer 7
