An Atwood machine consists of two masses, m^a = 6.7 kg and m^b = 8.4kg , connected by a cord that passes over a pulley free to rotate about a fixed axis. The pulley is a solid cylinder of radius R^0= 0.40m and mass 0.70kg . Determine the magnitude of the acceleration (a) of each mass.What percentage of error in a would be made if the moment of inertia of the pulley were ignored? Ignore friction in the pulley bearings.
