Kinematics plus a little extra

  1. Jul 14, 2015 #1
    1. The problem statement, all variables and given/known data
    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?

    2. Relevant equations

    Not sure, I'm guessing kinematics equations
    3. 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.
