less than the force of the moving passenger greater than the force of the moving car in the same direction as the car's motion in the opposite direction of the passenger's motion
I gave my students this multiple choice question: In a car accident, a seat belt helps prevent injuries by applying a force

Only one answer is correct among these 4 choices:
- less than the force of the moving passenger
- greater than the force of the moving car
- in the same direction as the car's motion
- in the opposite direction of the passenger's motion

Could you tell me which one is correct?

in the opposite direction of the passenger's motion
