1. The problem statement, all variables and given/known data If we want to pull a block with a weight of 5N attached to a rope that is just able to resist 20N. What is the maximum force that we can exert without breaking the rope? xD 2. Relevant equations Fnet (in y) = ma = F (applied force) - W (weight) 3. The attempt at a solution What I think is that: if the rope will just resist 20, and we already know that the weight of the block is 5N, then we should apply a 15N force right ?
