Design an experiment to determine the spring constant (k) for a bungee cord or other type of spring that you have at home.You will be using Hookes Law, and your final equation for k will be

where

g = gravitational constant

m = slope of the regression line

Becausegis a constant and has no error,kis dependent only on a single variable, namely the slopem.So you can use equation (1) (the single variable error propagation equation) from the first page for your error.

In the box below, use equation (1) to derive an expression for k.Use as many lines as you wish. You can type in the box or do it on a piece of paper and take a photo of it.
