Question:

An Atwood machine consists of two masses, mA= 63 kg and mB = 71 kg , connected by a massless inelastic cord that passes over a pulley free to rotate (Figure 1). The pulley is a solid cylinder of radius R = 0.40 mm and mass 5.0 kg. [Hint: The tensions FTA and FTB are not equal.]

Acceleration of each mass is 0.57 m/s2

What % error would be made if the moment of inertia of the pulley is ignored?

Express your answer using two significant figures.
