QUESTION3(11.38) An Atwood machine consists of two masses, mA= 6.9 kg and mB = 8.7 kg , connected by a cord that passes over a pulley free to rotate about a fixed axis. The pulley is a solid cylinder of radius R0 = 0.40 m and mass 0.80 kg . Part A Determine the magnitude of the acceleration a of each mass. Express your answer using two significant figures. Part B 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. Express your answer using two significant figures. (Error=%?)
