Answer:
Explanation:
Impulse: This can be defined as the product of force on a body and time.
The S.I unit of impulse is Ns or kgm/s.
mathematically, impulse can be expressed as,
I = F×t........................... Equation 1
Where I = impulse of the force on the car, F = Force, t = time
F = 4000 N, t = 0.2 s
Substituting into equation 1,
I = 4000×0.2
I = 800 Ns.
Thus the impulse impacted by the force = 800 Ns.
