<S02> Muzzle Velocity - No ROBOT may throw a ball with an exit velocity of greater than 12 m/s (26.8 mph).
As a reference, a ball traveling at this velocity when leaving the ROBOT at an angle of 30º from
horizontal with no spin will travel approximately 35 feet. A robot that violates this rule will be
considered unsafe per <S01>.
Does this include your current speed when the ball is fired in the muzzle velocity? Because the ball might go farther than 35 feet from the spot it was fired from if you were moving when you fired.

If the tank is moving FORWARD while the projectile is being launched, the same rule applies to the “muzzle velocity” although the imputed ground speed may be different.
But, it’s NOt a net sum game. There are laws of physics dealing with recoil, etc.
Same holds true if you’re back-peddling to get home and fire off one last Hail Mary shot in the opposite direction.
reminds me of the “two trains were traveling from Chicago to New York…”
since FIRST chose to use the term ‘Muzzel Velocity’ I think the answer is clear. It would be measured (tested) with the robot standing still.
The speed is measured relative to the ‘muzzel’ (launcher), not relative to the ground at all possible robot drivetrain speeds.
