Did you know that when a ball strikes the ground, its shape distorts? This distortion stores the energy that powers its rebound. The more its shape changes, the higher the ball will bounce.
The ball in this puzzle rebounds to half the height from which it is droped. Suppose it is dropped form a 1-meter height. What distance would the ball travel before it comes to rest?
Answer: Approximately 3 meters. The first fall is 1 meter. It rebounds to 1/2 meter, than falls 1/2 meter. So now we'are at 2 meters. Then the ball goes up and down 1/4 meter, ten 1/8 meter, then 1/16 meter, and so on. It continues this pattern until it comes to rest. If we were to add all of these distance up, we'd get: 1 +1/2+1/2+1/4+1/4_+1/8+1/8++1/16+1/16+...=3 meters
