Question

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 1 s:

(a) which vehicle experiences the greater force of impact?

(b) which vehicle experiences the greater change in momentum? which vehicle experiences the greater acceleration?

(C) why is the car likely to suffer more damage than the truck?

Answer 1

(a)During a collision, due to the action and reaction being equal and opposite, both the vehicles experience equal force. the vehicles

(b)Initial velocity of both V

Final velocity of both the vehicles = 0

=If M and m are the masses of the truck and the car respectively (M being much greater than m), Change in the momentum of the truck = Mx (0 Change in the momentum of the car = v) = - Mv mx (0 v) = -mv -
