in tests to choose the most comfortable shock absorbents, 3 cars are used, with the same mass "m", and the same springs, but different shock absorbents. the graphs show the changes in car height when passing over a bump (y=0 being the normal state of the car).
-Witch car has the best shock absorbent?
(P.S: i'm not sure if I've got the correct translation for "shock absorbents", but i hope you'll get what i mean)
The Attempt at a Solution
As far as i know, it's the changes in motion that cause discomfort not the movement itself, so, for the 3rd car, it returns almost immediately to it's original state, and for the 1st it vibrates violently, so both would be quite bad.
as for the 2nd, it's a compromise between the two, it ensures a smooth transition to the normal state.
i don't know if it's the correct answer, or I completely missed the point.
