A ball falls, rebounds to 72% of its previous height and falls again. After two bounces, the ball reached a height of 25cm. From what height was the ball dropped originally?

Max  Height after first bounce = 25/0.72 = 34.72cmOriginal Height from which the ball was dropped = 34.72/0.72 = 48.22 cm (2 decimal places)

48.225/72=.3472×100=34.72/72=.4822×100=48.2
