- Solve this problem the 'proper' way...
Nobody else on the internet is sketching chain like this. The sketch on point hopefully makes up for leaving the mic 6 feet away....
Use the conservation of energy to find the change in velocity of a chain as it slides off a table.
This solution assumes the chain and table are frictionless and the chain is of uniform linear mass density.
This problem shows up in calculus based physics courses such as AP Physics C Mechanics. It also appears in some calculus and differential equation texts.
Thank you so much for the awesome video! Really helps me in the confusing world of Calculus in Physics.
You're very welcome!
What about the height above the ground. There is more mass being affected by gravity as it slides, but the height of the chain above the ground decreases. Does this balance out? I am confused
can u do with friction?
Do you want to do the typical version of this problem where we consider the normal force as being the weight of chain on the table? Or are you looking for the more complicated version of the problem where we consider the tension in the vertical segment of chain as contributing to the normal force?
