Suppose a ball is dropped from a height of 16 feet. Each time it drops h feet, it rebounds 0.81h feet. Find the total distance t
Roman55 [17]
When the ball is first dropped, it falls h feet. On the first bounce, it rebounds 0.81h feet, which means on the second "drop" it must travel 0.81h feet again. On the second bounce, the ball rebounds 0.81(0.81h)=0.81^2h feet, and on the third drop falls the same distance. And so on.

So there are two directions to track:

\text{downward: }\displaystyle h+0.81h+0.81^2h+\cdots=\sum_{n=0}^\infty 0.81^nh
\text{upward: }\displaystyle 0.81h+0.81^2h+\cdots=\sum_{n=1}^\infty 0.81^nh

The total distance is the sum of these two:

\displaystyle\sum_{n=0}^\infty 0.81^nh+\sum_{n=1}^\infty 0.81^nh=h+2h\sum_{n=1}^\infty 0.81^n

Recall that for an infinite geometric sum, you have

\displaystyle\sum_{n=0}^\infty r^n=1+\sum_{n=1}^\infty r^n=\frac1{1-r}

provided that |r|. So the total distance traveled by the ball is

h+2h\left(\dfrac1{1-0.81}-1\right)\approx9.53h

Starting with a height of h=16 means the total distance is about 152.42 ft.

Since the y value is the same this isn't going to be hard to find out. all you need to do is add + 1 to the first x value enough times that you reach 10 which is 13 and the y value is the same so it's also a zero slope.
