Students are going to perform an experiment to determine the acceleration due to gravity, , in the lab using the setup as shown above. They are expected to find by plotting their data in a graph. The students have access to equipment commonly found in a high school physics laboratory, but the experiment must use the setup as shown above, which includes a flying toy of mass suspended from the ceiling by a light string of length . The toy travels in a circle at a fixed speed , and the string makes an angle with the vertical, as shown.
