The height a ball bounces is less than the height of the previous bounce due to friction. The heights of the bounces form a geometric sequence. Suppose a ball is dropped from one meter and rebounds to 95% of the height of the previous bounce. What is the total distance traveled by the ball when it comes to rest?

Respuesta :

We will need to find the limiting sum of the geometric series, which is given by:

[tex]S_\infty = \frac{a(1 - r^\infty)}{1- r}[/tex], a is the 1st term, and r is the common ratio.
[tex]S_\infty = \frac{1}{1 - 0.95} = 20[/tex]

Hence, the total distance travelled is 20 metres.
