week 4 the Trebuchet (it's a catapult)

For week 4 we used the trebuchet to test its distance  and what would happen. It was really cool and If you put more and more weights it would fire much higher and go longer. There was a string that would make it fire if you pulled it . The forces that were active on it were a pull,flight and a push. Where i think i am on the rubric is relational.
