1. The problem statement, all variables and given/known data
A stone hangs by a fine thread from the ceiling and a section of the same thread dangles from the bottom of the stone. 2. Relevant equations a. If a person gives a sharp pull on the dangling thread, where is the thread likely to break: below the stone or above it? b. What if the person gives a slow and steady pull? Explain your answer. 3. The attempt at a solution I think that the answer for a is below while for b the answer is above, but I don't know exactly how. Can someone please explain this in detail. Thanks

What happens to those tensions is the 2 kg stone is replaced by a 4kg stone? 6kg? 8kg? 12kg? 14kg? ...... That should give you a clue for part (b) Answer me that and I will give you a hint about (a) EDIT: for speed of calculation, and because each stone could have been a little heavier any way, use g=10 m/s^2
