What is the relationship between the required launch length and the change in velocity according to the kinematic equation?

The required launch length is proportional to the change in velocity.

Why are transportable pneumatic rail launchers of reasonable length not suitable for many applications?

They require acceleration values beyond human pilot tolerance.

What is the alternative perspective to the kinematic equation, particularly applicable to 'zero-length' launch methods?

Impulse-momentum equation.
