A car and a truck moving with the same velocity in opposite directions collide and collision lasts for `2 s`.
(i) Which vehicle experiences the greater force of impact?
(ii) Which vehicle has the smaller change in momentum?
(iii) Which one undergoes greater acceleration?
(iv) Which one is pushed farther?
(v) Which one is likely to suffer more damage?

Explanation

(i) On collision, both the car and the truck experience the same force as action and reaction are equal.
(ii) Again, both the vehicles experience the same change in momentum, because
force `=("change in momentum")/("time of collision")`
(iii) As acceleration `=("force" )/("mass")`
and mass of car is less than the mass of truck, therefore, acceleration of car is more than the acceleration of the truck.
(iv) Car is pushed farther than the truck, because car is lighter than truck.
(v) The car is likely to suffer more damage as it is lighter than the truck.
