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

AI Thread Summary
Calculating the splash radius of a rock dropped from a bridge involves understanding the rock's mass, shape, and the physics of its impact with water. Kinematic equations can help determine the rock's final velocity upon hitting the water, but the splash size is influenced by factors such as the rock's dimensions and shape. The discussion highlights the importance of defining the rock's "size" in terms of height, mass, and volume. A reference to a website on the physics of splash effects suggests that similar principles apply to different objects impacting water. Ultimately, while the physics can be analyzed, predicting the exact splash radius remains complex.

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.
