1. The problem statement, all variables and given/known data A block of mass m1 is attached to a block of mass m2 by an ideal rope passing over a pulley of mass M and radius R as shown. The pulley is assumed to be a uniform disc rotating freely about an axis passing through its center of mass (cm in the figure). There is no friction between block 2 and the surface. Assume that the pulley rotates counterclockwise as shown with an angular speed ω and that the rope does not slip relative to the pulley, and that the blocks move accordingly and do not topple or rotate. Consider the system to be formed by the pulley, block 1, block 2 and the rope. Calculate the magnitude of the angular momentum of the system about the center of mass of the pulley. Express your answer in terms of some or all of the variables m1, m2, M, R, ω and g. Type omega for ω 2. Relevant equations 3. The attempt at a solution Used formula L=Iw I=.25MR^2 then multiply by w so L=1/4*(M*R^2)*w. What am I doing wrong?
