Re: equation

This is not one of those cases where there is a standard equation - you have to derive it from the physics.

What kinds of physics do you think should apply here?

Note: I don't know what the falling mass is supposed to do.
Does it hit the surface of the water?
If so, does it float or sink?
If not: did it start below water-level, or is it next to the tank?
