The Polynomial 2-3 Motion-Law is not available directly with the Motion-Law Selector.
You can edit the start and end of a Flexible-Polynomial motion-law be the same as the Polynomial 2-3.
You can also use the Cubic Motion-Law, but specify 0 units/s for the Velocity at its start and end.
This segment is included for reference.
A different name for this motion-law is a Parabolic Velocity.
This motion-law is not usually recommended.
The maximum velocity is the lowest of the Traditional Motion-Laws.
Polynomial 2-3 with Flexible Polynomial Motion-Laws
If you can put a Flexible Polynomial motion-law before and after this segment, then it is possible to make sure the motion is continuous in position, velocity and acceleration.
