Question 1089773
<pre><font size = 5><b>
Let the first term be the ball's first 25-meter drop PLUS 
its 25(0.60) = 15-meter first upward bounce immediately 
following. That's 25+15 = 40 meters for the first term. 
Each term thereafter will consist of the ball's drop plus 
its upward bounce immediately following.  So the first 
term is 40 meters and the common ratio is 0.6.  The
formula for the sum of an infinite geometric series is:

{{{S[infinity]}}}{{{""=""}}}{{{a[1]/(1-r)}}}

{{{S[infinity]}}}{{{""=""}}}{{{40/(1-0.6)}}}

{{{S[infinity]}}}{{{""=""}}}{{{40/0.4}}}

{{{S[infinity]}}}{{{""=""}}}{{{matrix(1,2,100,meters)}}}
