# Find number of bounces the ball will make before it bounces less than a given number of meters?

Posted on 2012-09-03

Earlier following question was asked:

As part of a science experiment, you drop a ball from various heights and measure how high it bounces on the first bounce. The results of six drops are given below.

Drop height (m) 0.5 1.5 2 2.5 4 5

First bounce height (m) 0.38 1.15 1.44 1.90 2.88 3.85

How high will the ball bounce if you drop it from a height of 6 meters?

Is there a pattern here? I couldn't find a pattern.

This is high school Algebra 2 problem. It's not homework.

Follow up question is as follows:

To continue the experiment, you must find the number of bounces the ball will make before it bounces less than a given number of meters. Your experiment shows the ball's bounce height is always the same percent of height from which it fell before the bounce. Find the average percent that the ball bounces each time.

What do they mean by finding the number of bounces the ball will make before it bounces less than a given number of meters.?

Thank you!
