(a) Assume that we took these trials and plottedthe difference in the weights,??−??, on the ?-axis and the accelerationon the ?-axis.

Free body diagrams are also shown for both hanging masses. Using
separate instances of Newton's 2nd Law for these two masses, derive
a single theoretical equation that solves for the acceleration of the
system in terms of the unknowns and g. Hint: the tension should not
be one of these unknowns.
