Question

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. What impulse is imparted by this force to the car in kg m/s

Answer 1

Por the impulse, use the formula:

I = F * t

Now, we know:

4000 N = 4000 kg*m/s²

Replacing we have:

I = 4000 kg*m/s² * 0,200 s

Resolving:

I = 800 kg.m/s²

The impulse is 800 kg.m/s²
