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:
(a) Which vehicle experiences the greater force of impact?
(b) Which vehicle experiences the greater change in momentum?
(c) Which vehicle experiences the greater acceleration?
(d)Why is the car likely to suffer more damage than the truck?

Explanation

As acceleration =force/mass and force on each vehicle is same acceleration `prop 1/(mass)`
As mass of car is smaller , therefore, acceleration of car is greater than the acceleration of the truck.
