1. The problem statement, all variables and given/known data Two weights are connected by a very light flexible cord that passes over a 50 N frictionless pulley of radius .300 m. Pulley is a solid uniform disk and is supported by a hook connected to a ceiling. What force does the ceiling exert on the hook? There are two weights around each side of the disk, one is 75 N and the other is 125 N. Answer is 249 N. 2. Relevant equations I = 1/2 MR^2 F=ma 3. The attempt at a solution clueless..help!
