One-Dimensional Elastic Collision Simulation

In this game, you must employ the projectile equations to win.
The game consists of three levels, each of which must be completed by scoring at least 8 out of a possible 10 tries. In the first level, you must hit a ground target that shifts position after each attempt. In the second level, you will need to alter the ball’s trajectory to pass over a wall. In the third level, the target flies and changes position both horizontally and vertically in each trial.
