1. The problem statement, all variables and given/known data
a heap of chain is lying on a table with a hole. A small part of chain is released through the hole.calculate the velocity as a function of the length of the chain hanging vertically.
[2. Relevant equations
3. The attempt at a solution
if I take a mass element dm at a distance x from the hole,
then the force acting on it is
dF= (dm)g
then the acceleration is dF/m. this is equal to dV/dx
I am stuck now.
{ans is (2/3gy)1/2 }
