# The *Negligible* tank!

Classical Mechanics Level 2

A cylindrical tank of negligible mass is kept on a perfectly frictionless surface. Now it's being filled with an ideal liquid of density d upto a height H, after this a small hole is made at the bottom of the tank, the liquid as expected gushes out, due to which a force is experienced by the tank and the tank accelerates. Find the final velocity v of the tank when all the liquid drains out?

(Acceleration due gravity = g)
