- 1. In PYTHON please. I will upvote! Problem 1.8: Case Study: Bouncing Balls The program displays bouncing balls with control buttons. (Screenshot courtesy of Apple.) The program enables the user to click the + and - buttons to add a ball or remove a ball from the canvas and click the Stop and Resume buttons to stop the ball movements or resume them. Each ball has its own center location ( x,y ), radius, color, and next increment for its center position, dx and dy. You can define a class to encapsulate all this information, as shown in Figure 11.10. Initially, the ball is centered at (0,0), and dx=2 and dy=2. In the animation, the ball is moved to (x+dx,y+dy). When the ball reaches the right boundary, change dx to -2 . When the ball reaches the bottom boundary, change dy to -2 . When the ball reaches the left boundary, change dx to 2 . When the ball reaches the top boundary, change dy to -2 . The program simulates a bouncing ball by changing the dx or dy values when the ball touches the boundary of the canvas. Do problem 11.21 from the end of chapter 11 of your textbook. Below is the statement of the problem: Revise listing 11.9 to add two buttons--faster and slower to speed up or slow down the ball movement. See screen shot below for an example interface. It's up to you to choose by how much you want increase/decrease the ball's speed (you may experiment with few options)
