Calculating 'g' with Slope of Pendulum Graph

[physicsguy101]

Homework Statement

Using the slope from a graph of the square root of the pendulum's length vs period (which would be a linear relationship), calculate the experimental acceleration due to gravity.

Homework Equations

I'm trying to figure out what equation I can use to solve for 'g'.

I know that T = 2*pi*√(L/g), but will that help here? I need to use the slope of the graph in order to calculate g.


Thanks in advance!

Use the fact that √ (a/b) = √a/√b and get your equation in the form Y = MX so that the gradient is M.
