It's just an idealized problem for a Physics I course. Airdrag, density, changing gravity with height, curvature of the Earth and all those other variables you can think of isn't necessary for a problem where the distance traveled is only 55m. The error only becomes apparent at much greater distances, heights and velocities.
You can spend all day accounting for the different variables, and it'll probably give you an answer within 1-2% of the one you get with the kinematics formula.
It's never 100% correct anyway, most things end up being approximations.
What if the slingshot was placed on a treadmill going in the opposite direction?
They don't sell those in the US because it is a "choking hazard"
the puzzle or the plastic containers they come in?
Probably the puzzle pcs. Apparently we have no personal responsibility here in the US and need everyone to tell us what we can and can't do

And don't forget - you can win big prize money for being retarded. Like the guy that used the table saw after removing the blade guard or rip fence, and sued the company that made the saw because he lost some body parts.
And do you know why push lawn mowers in the US have a lever that has to be held or else the motor and blade are braked?And don't forget - you can win big prize money for being retarded.

Because some moron picked up his push lawn mower by the deck to clip his hedge. Seems he clipped a few digits as well......
