## John's Super Ball Experiment

## Check-In: Questions 17–21

John repeated his experiment using a super ball. Below is a graph of his data.

- Predict how high the super ball would bounce if it is dropped from a height of 60 cm.
- From what height should John drop the ball if he wants the ball to bounce 75 cm? Write your solution as a ratio.
- Are the variables drop height (
*D*) and bounce height (*B*) in proportion? How do you know? - Predict how high the ball will bounce if it is dropped from a height of
*D*= 240 cm. - Use John's Method to solve the problem and write a proportion. (Hint: = )
- Use Felicia's Method to solve the problem.
- Predict how high the ball will bounce if it is dropped from
*D*= 150 cm. Explain your reasoning.
