As part of a safety investigation, two 1900 kg cars traveling at 20 m/s are crashed into different barriers. part a find the average force exerted on the car that hits a line of water barrels and takes 1.3 s to stop.

-

Explanation:

We are given that

Mass of cars= m=1900 kg

Initial speed of car=u=20 m/s

Final speed of car=v=0

Time==1.3 s

We have to find the average force exerted on the car.

Average force=

Hence, the average force exerted on the car that hits a line of water barrels=-

this a false
