Write a simulation that simulates balls being fired from the bottom center of the screen at some angle that ranges between 70 and 110 degrees. Some force like Earth's Gravity should act on these balls so that they eventually fall down. Each time the user hits the space bar a new ball is fired.

*use the skeleton code below*
