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.
