CONVERGENCE OF A SERIES 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.
