Practice - Ball Bounce Activity

Ball Bounce

In this experiment you will drop a bouncy ball from a height of 2 m and observe how the height changes depending on the number of times the ball is allowed to bounce. 

The materials you will need: Measuring tape, bouncy ball, graphing calculator

1. Determine an equation that can be used to model the scenario. Why did you choose your model?  Why does a quadratic NOT make sense?

2. Determine the key features for your model (y-int, asymptote, domain/range, intervals of inc/dec) and interpret their meaning within the context of the activity.

3. Why do you think that your model does not have any x-intercepts?

4. Use your model to predict the height of the ball after the 13^th

8. If you were to repeat the experiment with the exact same ball but it was initially dropped from a height of 250 cm, calculate which bounce would have resulted in a height closest to 100 cm.
