Final answer:
The bouncing of a trailer on a highway can be explained by the concept of resonance. When a trailer is heavily loaded, it is more likely to resonate with the bumps and vibrations of the road. Conversely, when a trailer is nearly empty, it has a higher natural frequency, reducing the likelihood of resonance and resulting in less bouncing.
Step-by-step explanation:
The bouncing of a trailer on a highway can be explained by the concept of resonance. Resonance occurs when the frequency at which the trailer bounces matches the natural frequency of the trailer system
When a trailer is heavily loaded, it has a lower natural frequency, making it more likely to resonate with the bumps and vibrations of the road, resulting in a slow up and down bouncing motion. On the other hand, when a trailer is nearly empty, it has a higher natural frequency, which reduces the likelihood of resonance and results in less bouncing.
