It was a dark and stormy night, when suddenly you saw a flash of lightning. five-and-a-half seconds later you heard the thunder. given that the speed of sound in air is about 340 m/s, how far away was the lightning bolt?

The answer is; A

As the ball bounces, the kinetic energy is lost as heat and therefore the initial energy of the ball reduces. The ball, therefore, bounces to a less height with each bounce. As the ball hits the floor, it deforms and reforms again. This compression and decompression including friction between the ball and floor are some of the contributors to the loss of its energy to heat (that also warms it up).
