Answer:
C.
Step-by-step explanation:
Because if the impulse experienced by a car (2,000 kg), is 4,000 kg-m/s, then your just subtracting 2,000 from 4,000 which gives you 2,000 kg-m/s or in other words 2.0 kg-m/s.
I think it is. If it's the wrong answer please tell me, I really hope that this helps you. ..
