CASTLE CRASHERS

ABSTRACT

The purpose of this project is to find out if a model ballista or trebuchet will shoot farther. The way the experiment was performed is that the ballista was fired five times and the distances were measured. Then the trebuchet was fired five times and the distances were measured. After the measurements were made they were averaged and that gave us the conclusion.
