A tennis ball noticeably changed shape when it bounces on the ground. This compression is evidence of elastic energy. Assume that the mass of the ball is 0.057kg. The spring constant of a tennis ball is 440 N/m, meaning that it take 440 N of force to compress the ball by 1 meter (of course a tennis ball is much smaller than 1 meter, but the proportion 4.4N per 1cm also works). How much elastic energy is stored in the tennis ball when it is compressed by 0.03 m?
