4. You attach a mass, M, to a string that is wrapped around a pulley with moment of inertia I and radius R. Then you measure the height of the mass as a function of time as the mass falls, unwinding the string around the pulley. By solving Newton's Laws, you find the relationship between the moment of inertia and the measurable quantities of the experiment is I = (g/a-1)MR. The acceleration of the mass determined by graphing the data is found 1.6 0.2m/s when a mass of 0.56 0.01kg is attached to a pulley with radius 0.15 0.01m. The acceleration due to gravity is 9.81m/s2 and can be treated as a known constant without uncertainty. Based on this information, what value should you state is the measured moment of inertia of the pulley? to be a =
