Chapter 4 Physics! For instance, consider the Atwood Machine m 2 m 1 Two masses are connected by a string that passes over a light, frictionless pulley. Describe the motion of one of the masses. What will happen when we release the pulley? 123 12% 29% 59% 1. Weights will move with fixed velocity 2. Weights will move with fixed velocity 3. Weights will move until they reach a stable configuration then stop Nevermind, question error
