Can You Calculate the Splash Radius of a Rock Dropped from a Bridge?

[Entr0py]

Homework Statement

I was wondering that, if you are standing above a bridge with a height h and throw a rock in your hand with mass m and initial velocity v naught of 0, could you calculate how big of a splash said rock makes when it hits the water?

Homework Equations

Not sure, I'm guessing kinematics equations

The Attempt at a Solution

Well maybe I could plug in values for mass, initial velocity, final velocity, acceleration. But I don't know if it's possible to find how big (what is the radius) of the splash the rock creates.

Do you think the size and shape of the rock might be relevant?

Of course, and thanks for pointing that out. Let's say the rock is a perfect sphere and what do you mean by its size? Its mass, length, volume?

By "size" I mean how big it is.

Let's say it's x meters tall.
