[zizodev]

Homework Statement

consider two balls of exactly the same size and material.
Ball A is filled with air and ball B is filled with water.if dropped from a height of 100 feet,which will hit the ground first?

Homework Equations

U=mgh.

The Attempt at a Solution

i suggest the ball B will hit the ground first because the water is more denser than air.

Nice hunch, but can you supply a quantitative reason?
