The masses attached to each side of an ideal Atwood's machine consist of a stack of five washers, each of mass m, as shown in the figure below. The tension in the light string is T0. When one of the washers is removed from the left side, the remaining washers accelerate and the tension decreases by 0.330 N. (Assume that the pulley is massless and frictionless.)
a) Find m.
b) Find the new tension and the acceleration of each mass when a second washer is removed from the left side.
