Web0. If your pulley has mass, you have to consider the rotational inertia of it. Inertia is the tendency to resist movement. Your rope does not have equal tensions. Consider T 1 and T 2 where T 1 is the tension on the side of M 1 and T 2 is the tension on the side of M 2. Assuming M 1 is greater than M 2, we have M 1 g − T 1 = M 1 a, T 2 − M ...
