    1. The problem statement, all variables and given/known data

    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?

    2. Relevant equations
    U=mgh.
    3. The attempt at a solution

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