rock on a string on the ceiling??!
I'm stuck on this problem... any ideas??
A stone hangs by a fine thread from the ceiling and a section of the same thread dangles from the bottom of the stone. If a person gives a sharp pull on thedangling thread, where is the thread likely to break: below the stone or above it? What if the person gives a slow and steady pull? Explain your answers.
We're in a chapter about Newton's Laws
I know the rock and gravity are pulling down on the string. And the ceiling is pulling up... and without touching the string the forces of the rock on the string and the ceiling on the string create a net force of zero... but what is the effect of acceleration (you pulling on the string)??
THX
