Dr. Deduction has a peculiar penchant for using elaborate experimental se- tups and convoluted calculations to determine physical quantities that could have been obtained by just taking a direct measurement. In her latest exper- iment, she shuns her scale in favor of an indirect method to determine the mass of 3 identical pulleys, each of radius R (the pulleys are solid cylinders).

Dr. Deduction has a peculiar penchant for using elaborate experimental se-
tups and convoluted calculations to determine physical quantities that could
have been obtained by just taking a direct measurement. In her latest exper-
iment, she shuns her scale in favor of an indirect method to determine the
mass of 3 identical pulleys, each of radius R (the pulleys are solid cylinders).
She hung 2 masses of mass m and 2m from the pulleys as drawn below. When
released, the 2m mass is observed to fall with an acceleration a. Determine
the mass, M, of one of the pulleys.
