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 β’ rn β 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)

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is Ξ±. part a: how can you use trigonometric ratios to calculate the direction Ξ± of a general vector v = < x, y> similar to the diagram? part b suppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
