Answer:

A. 1.8x10⁵

Explanation:

For this question we have

72km/h = speed

Total mass = 2250kg

Stopped at t = 0.2250s

To get average force acting on this car on collision:

72km/3.6 = 20m|s

Impulse = ∆p

This implies:

F∆t = m∆v

F = m∆v/∆t

= 2250x20/0.250

= 180000

= 1.8x10⁵

Therefore option A is correct.
