Suppose a child drives a bumper car head on into the side rail, which exerts a force of 4000 N on the car for 0.200 s. (a) What impulse is imparted by this force?

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.
