This question is on behalf of a colleague who is planning a new research
study:

"I am writing a research protocol on the response of the neck and head
to unexpected accelerations/decelerations. In order to get the study
approved, I must be able to state that the subjects will not be in
danger of injury. I thought about specifying that we will stay within
the acceleration limits for amusement park rides, but I have not been
able to find such limits. Does anyone have a reference that describes
safe limits for amusement park rides, or other relevant limits? I
understand that the criteria may be in terms of the first derivative of
acceleration (jerk) or the second derivative of acceleration (snap)."

Any help would be greatly appreciated.

Thanks.
