1. The problem statement, all variables and given/known data "Using the pulley system shown to lift the heavy dresser, the person is applying a force of 150N to the end of the rope. Which of the following is closest to the maximum mass of the dresser that can be lifted with this force? [Ignore weight & friction from pulleys/rope.]" A) 46kg B) 92kg C) 110kg D) 150kg E) 180kg 2. Relevant equations Newton's 2nd & 3rd laws 3. The attempt at a solution So she's pulling with 150 N and there are three pulleys connected to the dresser, so her effort is tripled. 450N lifts the dresser and so the mass is 46kg?
