YOUR ASSIGNMENT: Ball Bounce You have chosen one ball; now you will predict how high it bounces on the 10th bounce. In this assignment, you may work alone, with a partner, or in a small group. Discuss the results of your work and/or any lingering questions with your teacher. 1. Circle the ball you chose. (1 point) Basketball Tennis ball Table-tennis ball Writing an Equation 2. Assume that the ball rebounds the same percentage on each bounce. Using the initial drop height and the height after the first bounce, find the common ratio, r. Note: Round r to three decimal places. Use this formula: (3 points: 2 points for showing your work, 1 point for the answer) r = 3. State the general version of the recursive formula. (1 point) 4. Find the recursive formula for the height of your ball. Remember that the 1st term, a1, is the height of the ball on the first bounce.(2 points) 5. Fill out the following table for your ball's height after the first 3 bounces. Note: Let n = bounce number. The height on the 1st bounce, n = 1, is given. (2 points:) Bounce n Height First bounce 1 Basketball: 54 inches Tennis ball: 58 inches Table-tennis ball: 26 cm Second bounce 2 Third bounce 3 6. Write the explicit formula for the geometric sequence of the height of the ball on the nth bounce. Use the formula an = a1 • rn – 1. Remember that the 1st term, a1, is the height of the ball on the first bounce. (2 points) Solving the Problem 7. Using the explicit formula, find the height of the ball on the 10th bounce. (4 points: 2 points for showing your work, 2 points for the answer) Taking Time to Reflect 8. What are some factors that could affect the ball's bounce? Why might a ball bounce higher or lower than the regulated height? (1 point) 9. For the sport you chose, why would it matter if a player used a ball that bounced higher than the regulation? (1 point)
