750 N 1500 N 3000 N 6000 N
I gave my students this multiple choice question: A 1500 kg car increases its speed by 2 m/s for each second of travel. What is the net force acting on the car?

Only one answer is correct among these 4 choices:
- 750 N
- 1500 N
- 3000 N
- 6000 N

Could you tell me which one is correct?

3000 N
