Im doing my physics A2 coursework on the factors that effect the range of a 
projectile launched from a model trebuchet. I havnt really been able to find 
much that i understand easily, everything is either too detailed or not enough.

The main thing that i want to know is the effect of having the projectile 
attahed to a length of string on the throwing arm. What sort of formulaes and 
physics principals would i need to work this out? I havnt decided wether to 
use it yet or not. Would it still be a valid trebuchet without the string?
Im going to be changing the mass of the counterweight (not fixed), so i want to 
be able to keep everything else fairly consistant. With the string, would it 
vary the launch position too much?
