Answer:
The magnitude of its impulse is 250 N-sec.
Step-by-step explanation:
Given that,
Mass of car = 2000 kg
Force = 500 N
Time = 0.5 sec
We need to calculate the impulse
Using formula of impulse

Where, F = force
= time
Put the value into the formula


Hence, The magnitude of its impulse is 250 N-sec.
