A large truck and a car both moving with a velocity of magnitude v have a head on collision and both of them come to a halt after that. If the collision lasts for 1s :
Which vehicle experiences the greater force of impact

Explanation

Let mass of truck=M
mass of car =m
velocity of truck =v
velocity of car= -v
time for collision lasts t=1s
On collisions, both the vehicles experiences the same force, as action and reaction are equal.
