I’ve accelerated at about this rate on a catapult off of a U.S. aircraft carrier and it was super smooth and in fact quite exhilarating. Before I did so I spoke with the catapult operator who explained that it’s not just the total rate of acceleration, it’s how you apply it. You have to use some pretty serious science to make the rate of acceleration constant over the two or three seconds so you don’t snap the pilots’ or the passengers’ necks. Unfortunately for the designers of this ride, the last Japanese carrier was decommissioned in 1945.

That’s my understanding as well why there were problems with the incredible acceleration forces the electromagnetic system in the Ford was producing.

Did you have to swim back or did they pick you up?
What is a change in position? Velocity
What is a change in velocity? Acceleration
What is a change in Acceleration? Snap
What is a change in snap? Crackle
What is a change in crackle? Pop
Yes those are real things (derivatives) and their terms
Jerk is the rate of change of acceleration. You have to pay close attention to jerk when designing such a system.
