1. Program the calculator to bounce a ball. The ball will be dropped from a
given height, with a given bounce factor (the percentage the ball bounces up
of the distance dropped). The number of bounces will also be requested.
Repeated runs of the program, with a fixed height and fixed bounce factor,
will allow you to examine the convergence of the series. The series is the
sum of the distance traveled by the ball in its bounces.
2. Create a new program with the name BOUNCE. Enter the following program
and remember to press ENTER at the end of each line. If you make a mis
take, use the calculator’s editing features to correct the error.
