A student drops a ball and measures the height the ball reaches after each bounce. She recorded the data in a table as shown.

Bounce numberMaximum Height after the bounce (cm) 1, 2,3,4 112,

89.6 ,71.68 ,57.32

1. From what height was the ball dropped? Show how you deduced your answer. (3 pts)
2. What percentage of the previous height will the ball reach on its next bounce? (2 pts)
3. On which bounce was the height reached less than 10 cm? (3 pts)
4. What was the height the ball reached after the 6th bounce? (2 pts)
5. Name a limitation to this mathematical model.
