Write a program to simulate the linear, twodimensional motion of a filled circle inside a given rectangular area. The circle is to be given an initial position and velocity, and the circle is to rebound from the walls with the angle of reflection equal to the angle of incidence.

Problem 11

Convert the program of the previous exercise into a two-player ball and paddle game by replacing two opposite sides of the rectangle with short line segments that can be moved back and forth along each of the rectangle edges. Interactive movement of each line segment simulates a paddle that can be positioned to prevent the bouncing ball from escaping that side of the rectangle. Each time the circle escapes from the interior of the rectangle the score of the player assigned to the opposite side is increased. Initial input parameters include circle position, direction, and speed. The game scores can be displayed in one corner of the display window.

Problem 12

Modify the ball and paddle game in the previous exercise to vary the speed of the bouncing ball. After each successful block by a player, the speed of the ball is incremented by a small amount.

Problem 17

Write a program to implement the motion of a bouncing ball using dynamics. The motion of the ball is to be governed by a downward gravitational force and a ground-plane friction force. Initially, the ball is to be projected into space with a given velocity vector.

Problem 18

Write a program to implement dynamic motion specifications. Specify a scene with two or more objects, initial motion parameters, and specified forces. Then generate the animation from the solution of the force equations. (For example, the objects could be the earth, moon, and sun with attractive gravitational forces that are proportional to mass and inversely proportional to distance squared.)
