BONUS POINTS (10)

A seven kilogram bowling ball and a 0.5 kg softball are dropped from a second story window at the same time. We all know that (with air resistance negligible) the two balls will hit the ground at the same time. Since the bowling ball weighs more, that means that the gravitational force of the earth is greater on the bowling ball. If that net force is greater, then why do the two balls hit the ground at the same time?

Provide a full explanation that could be published in a newspaper to explain this phenomenon to someone who has not had physics. You may want to include sketches, mathematical equations and a discussion of Newton’s Second Law.
