Final answer:
The bouncing of a trailer on the highway can indicate whether it is heavily loaded or nearly empty. A heavily loaded trailer will have a lower natural frequency and bounce more slowly. A nearly empty trailer will have a higher natural frequency and bounce more quickly.
Step-by-step explanation:
The bouncing of a trailer on the highway can be used to determine whether it is heavily loaded or nearly empty. If the trailer is heavily loaded, it will have a lower natural frequency and will bounce more slowly. Conversely, if the trailer is nearly empty, it will have a higher natural frequency and will bounce more quickly.
This is because the natural frequency of an object depends on its mass. A heavier object will have a lower natural frequency, while a lighter object will have a higher natural frequency.
Therefore, based on the observation of a slow bouncing trailer, it is more likely that the trailer is heavily loaded.
