Car Oscillation Amplitude: Frequency & Constant Values

[Jamessamuel]

Homework Statement

The graph (see image in part 3) illustrates how the amplitude of a car's vertical oscilltions vary withthe frequency of an oscillating surface. I was asked to state the amplitude of the oscillation of the surface. I was told It stayed constant.

The Attempt at a Solution

I narrowed it down to x and y. However I cannot justify one over the other.

I was asked to state the amplitude of the oscillation of the surface. I was told It stayed constant.

And you can clearly see where the resonance is. Now, when do you think that the car's amplitude most closely follows the oscillation of the surface - at a very low frequency (for example when the oscillation period is 10 minutes) or at resonance?

The given curve is a bit misleading. The right-hand tail should be asymptotically zero.

Might be, might it not?

Svein has the good clue for you.

Sure, the curve shown doesn't rule it out, but it could be made clearer.
