The seat is at rest relative to the seated passenger, since it has the same velocity
Explanation:
We say that an object is at rest in a certain reference frame when the object is moving at the same velocity of the reference frame.
In this problem, the reference frame is the one moving together with the passenger (and the car): therefore, the object at rest in this reference frame will be the object moving at the same velocity of the passenger and the car.
Let's analyze each option:
- The seat --> correct. The seat is moving at the same velocity of the passenger, so it is at rest in his frame of reference.
- The trees along the road --> false, since they are not moving at the same velocity of the car.
- The road --> false, since they are not moving at the same velocity of the car.
- The wheels of the car --> false: although the wheels are moving together with the car, they are also rotating about their axis, so they have an additional (circular) motion that the car doesn't have, so they are not at rest in the passenger's frame of reference.
