Catapult Projectile Range: Calculate w/Varied Mass

[1234asdf]

a catapult that shoots at 45 degrees, with counterweight on one side.
the catapult is similar to a see-saw, where projectile is placed on one end, and the counterweight to another end.
the counterweight is lifted to a 45degrees and released.

is there any way to find the theoretical range of the projectile... when changing the projectile mass.

Welcome to PF,

If one ignores air resistance and assumes that the launch velocity is invariant, then the range of the projectile will be independent of it's mass.

thanks for the prompt reply.
i was wondering whether there are any equations to find the theoretical range of the projectile been thrown off the catapault. as I am comparing my results to the theoretical results.
