If three balls of different materials were dropped at the same time from the same height, which would hit the ground first? (Assume there is no air resistance.)

The three balls would hit the ground at the same time.

Explanation:

As Galileo Galilei proved with an experiment in which he put in free fall different objects of different mass, but the same shape, all objects fall with the same acceleration when are allowed to free falling. So, if the initial conditions were the same (height, initial velocity, and time), the three balls would hit the ground at the same time, no matter which material they are made of.

e) none of the above answers are correct

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
