1. The problem statement, all variables and given/known data 2. Relevant equations W = F d F = ma 3. The attempt at a solution so in order to get the whole chain on the table, we need to pull the chain 0.65 meters onto the table. since 0.65 meters is hanging off the table, the gravity is acting on it, therefore F=ma where m is half the chain (8kg /2 = 4kg) and a = gravity(g), which is 39.2 N,since we work against this force we need to find the force required to pull 8 Kg a distance of 0.65m and then subtract 39.2 N. is this the correct approach?
