Question 222445
<font face="Garamond" size="+2">


After the first bounce, the ball will go up *[tex \Large 13.5\ \cdot\ 0.6].  After the second bounce, the ball will go up 60% of that, or *[tex \Large (13.5\ \cdot\ 0.6)\ \cdot\ 0.6].  But that is the same as *[tex \Large 13.5\ \cdot\ 0.6^2].  Following the pattern, after the 38th bounce, the ball will go up:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 13.5\ \cdot\ 0.6^{38}] feet


Works out to about *[tex \Large 150 \AA].  About half the thickness of a coarse black human hair.
