question 3
assume you are in your car and youre stopped at a red light. when the light turns green you press the gas pedal and accelerate forward. a small air freshener hanging from your rear view mirror will appear to swing in which direction?
a. forward
b. backward
c. sideways
d. it will not move

Explanation:

According to Newton's first - law of motion (inertia), when the car accelerates forward, the air freshener, which was initially at rest, tends to stay at rest relative to the non - accelerating frame. So it appears to swing backward relative to the accelerating car.

Answer:

B. backward
