Find the average force exerted on the car that hits a line of water barrels and takes 1.6 s to stop.

We will find the average forces exerted on 1.60 s to stop, if we have two 1600 kg cars travelling at 18 m/s that are crashed into different barriers. 

The formula we will be using is F = mv/t, When the question are looking for the car that hits a line of water barrels and takes 1.6s to stop.
F = mv/t
F = 1600 kg * 18 m/s) / 1.80s 
F = 16000 N
