What materials do we need to measure acceleration due to gravity?

[Patrick Bateman]

Hello, I am a student in AP Physics and we have hit a wall for one of our labs. My group has been tasked with finding "little g" otherwise known as acceleration due to gravity. We HAVE to use the following materials in our experiment.

-a pulley
-string
-2 masses (kg weights)
-a steel frame
-measurement and recording devices

We suspended the two weights on opposite sides of the pulley and we are measuring how far and fast the heavier mass falls. We thought we had the correct possible formula but it have us a wrong answer. We have to assume that we don't know g before hand. Here is a picture of our formula.

Please help me out.

Your picture is unreadable. Please type out the equations, and define your variables.

Never mind. I deduced the answer. Thank you for your response though.
