Final answer:
In a car moving with constant velocity on a highway, five examples of objects at rest relative to the car are a passenger's bag on the seat, a smartphone on the dashboard, a beverage in the cup holder, the rearview mirror, and the GPS system. These objects are not accelerating relative to the car and hence are considered to be at rest within the car's inertial reference frame.
Step-by-step explanation:
If a car is moving on a highway with constant velocity, it means that it is not accelerating and is moving at a constant speed in a straight line. Consequently, any object within the car that is not accelerating relative to the car is at rest with respect to the car. Here are five examples of objects which may be considered at rest with respect to the car:
- A passenger's bag placed on the seat next to them.
- A smartphone lying on the dashboard.
- A beverage in the cup holder.
- The rearview mirror attached to the car.
- The GPS navigation system fixed to the car's interior.
According to Newton's first law of motion, these objects will remain at rest or in uniform motion (in this case, moving with the car at a constant speed) unless acted upon by an external force. This is due to the car and the objects inside forming an inertial reference frame where the laws of physics behave in predictable ways, assuming no external forces are affecting them.
