Let v be the velocity at the surface of liquid. Then from continuity principle, velocity at the orifice will be 3v.
From Bernouli's principle, we have,
where P = atmospheric pressure, 
is the density of the liquid.
Solving above equation for v, we have
differentiating both sides with respect to time, we get
Acceleration is negative as velocity is decreasing, as H is decreasing.
Note, acceleration is constant, it does not depend on the value of H
Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
