I was wondering if any of you had the chance to calculate the speed of your catapults. If so, would you mind sharing? We want to see how other teams are doing in terms of speed, so we have an idea of what speed to shoot for.
@skate17 we are looking for the speed of the catapult arm as it fires. Is there a way to find the speed given gear ratio and motor type?
No, there is no way to calculate from there. You could theoretically calculate from mass (including ball(s)), mass distribution (including ball(s)), elastics, behavior of the elastics, and the way the elastics are stretched. But that would be really hard.
Better would be to use it, film the projectile, and determine from the film.
