1. The problem statement, all variables and given/known data Two weights (one is 125 N, other is 75 N) are connected on each side by a very light flexible cord that passes over a 40.0 N frictionless pulley of radius 0.300 m. The pulley is a solid uniform disk and is supported by a hook connected to the ceiling. What force does the ceiling exert on the hook? 2. Relevant equations 3. The attempt at a solution I'm not really sure about what the question is asking... wouldn't the the force on the hook be the tension in the hook, which would be equal to the weight of the pulley plus the 125 & 75 N weights?
