How does mass affect the launch of a catapult and the projectile flight??

1. The problem statement, all variables and given/known data
How does the mass of the projectile affect the projectile as it is being lauched and after it is launched?

Could your catapult launch a tennis ball and a boulder equally well?
Once in flight, explain what the effect of the mass of the projectile is.

2. Relevant equations

N/A

3. The attempt at a solution
I know that the mass does not change the flight of the projectile. Right?

I do not know what to put for it being launched though..

If I put :

Mass does not affect anything, would that be right?

I don't really know what the question mean when it says launch equally well. Does it mean cover the same distance? Anyway this is what i think :a more massive object will have a higher momentum if both are given the same initial velocity and thus higher inertial which means air resistance will play a less significant part.
