Textbook Question
Chapter 13, Problem 12CQ
A helium-filled balloon is tied to a light string inside of a car at rest. The other end of the string is attached to the floor of the car, so the balloon pulls the string vertical. The driver now accelerates forward. Which way does the balloon move, forward or backward, or does it not move? Justify your reasoning with reference to buoyancy. (If you have a chance, try this experiment yourself—but with someone else doing the driving!)
