An Atwood machine consists of two masses, = 6.6 and = 8.0 , connected by a cord that passes over a pulley free to rotate about a fixed axis. The pulley is a solid cylinder of radius = 0.40 and mass 0.80 . Determine the magnitude of the acceleration of each mass. What percentage of error in would be made if the moment of inertia of the pulley were ignored? Ignore friction in the pulley bearings.
