When a table tennis ball falls from a high altitude, the height of the bounce is about 2/5 of the drop height. If a table tennis ball falls from a height of 12.5m, bounces and then falls again, what is the height of the third bounce? ?
乒乓球从高空落下，弹起的高度约是落下高度的(2/5)，如果一个乒乓球从12.5m的高处落下，弹起后再落下，那么第三次弹起的高度是多少米？
