1. The problem statement, all variables and given/known data A mass (M1 = 5.0 kg) is connected by a light rope to a mass (M2 = 4.0 kg) which slides on a smooth surface, as shown in the figure. The pulley (radius = 0.20 meter) rotates about a frictionless axle. The acceleration of M2 is 3.5 m/s2. What is the moment of inertia of the pulley? https://ce.byu.edu/courses/univ/694820121006/media/l10g8.gif 2. Relevant equations I=mr^2 3. The attempt at a solution I have no references in my textbook as to how to approach this sort of problem. I'm not sure where I should even begin.
